9.10.8 Timers (TA0, TA1, TA2, TA3 and TB0)

The TA0, TA1, TA2 and TA3 modules are 16-bit timers and counters with three capture/compare registers each. Each timer supports multiple captures or compares, PWM outputs, and interval timing (see Table 9-12 and Table 9-13). Each timer has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers. The CCR0 registers on both TA0 and TA2 are not externally connected and can only be used for hardware period timing and interrupt generation. In Up mode, they can be used to set the overflow value of the counter.

(1) This is the default functionality that can be remapped by the TAxRMP bit of the SYSCFG3 register. Only one selected port is valid at any time.
(2) This is the remapped functionality controlled by the TAxRMP bit of the SYSCFG3 register. Only one selected port is valid at any time.

The interconnection of Timer0_A3 and Timer1_A3 can be used to modulate the eUSCI_A pin of UCA0TXD/UCA0SIMO in either ASK or FSK mode, with which a user can easily acquire a modulated infrared command for directly driving an external IR diode. The IR functions are fully controlled by SYS configuration register 1 including IREN (enable), IRPSEL (polarity select), IRMSEL (mode select), IRDSSEL (data select), and IRDATA (data) bits. For more information, see the SYS chapter in the MP430FR4xx and MP430FR2xx Family User's Guide.

The Timer_B module feature the function to put Timer_B all outputs into a high impedance state when the selected source is triggered. The source can be selected from external pin or internal of the device, it is controlled by TBxTRG in SYS. For more information, see the SYS chapter in the MP430FR4xx and MP430FR2xx Family User's Guide.

Table 9-17 lists the Timer_B high-impedance trigger source selections.
