PRODUCTION DATA
AM273x includes four, Multi-Buffered Serial Peripheral Interface (MIBSPI) master interfaces. Two of these interfaces are intended for external MCU, PMIC, EEPROM, Watchdog, and other system-level communication and are labeled as MSS_MIBSPI. The other two interfaces are intended for independently mastering SPI device sensors and are labeled as RCSS_MIBSPI.
Additionally, both the MSS and RCSS MIBSPI have a device-level implemented host interrupt request input signal path. These signals are intended to allow an attached SPI device to signal the AM273x MCU host device of any required action on the attached device. These signals are labeled as HOST_IRQ. See below Table 6-12 highlighting these MIBSPI host IRQ signals. See the AM273x Technical Reference Manual for more information on all features of the MIBSPI peripheral.
Signal Name | Signal Description |
---|---|
MSS_MIBSPIA_HOSTIRQ | MSS MIBSPIA host interrupt request |
RCSS_MIBSPIA_HOSTIQ |
RCSS MIBSPIA host interrupt request |
RCSS_MIBSPIB_HOSTIRQ |
RCSS MIBSPIB host interrupt request |
