5.11 Interrupts

Table 5-12 lists the TPS65919-Q1 interrupts.

These interrupts are split into four register groups (INT1, INT2, INT3, and INT4) and each group has three associated control registers which are defined as follows:

    INTx_STATUSReflects which interrupt source has triggered an interrupt event
    INTx_MASKUsed to mask any source of interrupt, to avoid generating an interrupt on a specified source
    INTx_LINE_STATEReflects the real-time state of each line associated to each source of interrupt

The INT4 register group has two additional registers, INT4_EDGE_DETECT1 and
INT4_EDGE_DETECT2, to independently configure rising and falling edge detection (respectively).

All interrupts are logically combined on a single output line, INT (default is active low). The INT line is used as an external interrupt line to warn the host processor of any interrupt event that has occurred within the device. The host processor must read the interrupt status registers (INTx_STATUS) through the control interface (I2C) to identify the interrupt source. Any interrupt source can be masked by programming the corresponding mask register, INTx_MASK. When an interrupt is masked, the associated event-detection mechanism is disabled. Therefore the corresponding STATUS bit is not updated and the INT line is not triggered if the masked event occurs. If an event occurs while the corresponding interrupt is masked, that event is not recorded. If an interrupt is masked after it has been triggered (the event has occurred and has not been cleared), the STATUS bit would reflect the event until the bit is cleared. While the event is masked, the STATUS bit will not be over-written when a new event occurs.

Because some interrupts are sources of ON requests (see Table 5-12), source masking can mask a specific device switch-on event. Because an active interrupt line, INT, is treated as an ON request, any interrupt that is not masked must be cleared to allow the execution of a sleep sequence of the device, when requested.

The polarity of the INT line and clearing method of interrupts can be configured using the INT_CTRL register.

An INT line can be triggered in either SLEEP or ACTIVE state, depending on the setting of the OSC_THERM_CTRL.INT_MASK_IN_SLEEP bit.

When a new interrupt occurs while the INT line is still active (not all interrupts are cleared), then the following occurs:

  • If the new interrupt source is the same as the one that has already triggered the INT line, the interrupt can be discarded or stored as a pending interrupt depending on the setting of the
    INT_CTRL.INT_PENDING bit.
    • When the INT_CTRL.INT_PENDING bit is active, then any new interrupt event occurring on the same source (while the INT line is still active) is stored as a pending interrupt. Because only one level of pending interrupts can be stored for a given source, when more than two events occur on the same source, only the last event is stored. While an interrupt is pending, two accesses are required (either read or write) to clear the STATUS bit: one access for the actual interrupt and the other for the pending interrupt. Two consecutive read-write (R/W) operations to the same register clear only one interrupt. Another register must be accessed between the two R/W clear operations.

      • For example of a clear-on-read operation, when the INT signal is active, read all four INTx_STATUS registers in sequence to collect the status of all potential interrupt sources. The read access clears the full register for the active or actual interrupt. If the INT line is still active, repeat the read sequence to check and clear pending interrupts.

    • When the INT_CTRL.INT_PENDING bit is inactive (default), then any new interrupt event occurring on the same source (while the INT line is still active) is discarded. Two consecutive R/W operations to the same register only clear one interrupt. Another register must be accessed between the two R/W-to-clear operations.
  • If the new interrupt source is different from the one that already triggered the INT line, then the interrupt is stored immediately in the corresponding STATUS bit.

To clear the interrupt line, all status registers must be cleared. The clearing of all status registers occurs by using a clear-on-read or a clear-on-write method. The clearing method is selectable though the INT_CTRL.INT_CLEAR bit. When this bit is set, the clearing method applies to all bits for all interrupts.

The two different clear operations are defined as follows:

    Clear-on-readRead operation on a single status register clears all bits for only this specific register (8 bits). Therefore, a read operation of all the four status registers is required to clear all the interrupts requests. When the four read operations are complete, if the INT line is still active then another interrupt event has occurred during the read process. Therefore, the read sequence must be repeated.
    Clear-on-writeThis method is bit-based; setting a specific bit to 1 clears only the written bit. Therefore, to clear a complete status register, write 0xFF. Writing 0xFF to all four status registers is required to clear all the interrupt requests. When the four write operations are complete, if the INT line is still active then another interrupt event has occurred during the write process. Therefore the write sequence must be repeated.
