Each timer can send or receive stimulus to/from the external (off-chip) system. In the device all timers are configured to output a PWM pulse or receive an external event signal used as a trigger to capture the current timer count.
Figure 12-2470 shows the external system interface for the timers, and Table 12-4708 describes the timer inputs and outputs.

Each MCU_TIMER_PO_GPOCFG and TIMER_PO_GPOCFG signals are used as an output enable to control the function of the MCU_TIMER_IO[3-0], and respectively TIMER_IO[11-0], as the PWM output (PO_GPOCFG = 0) or capture input (PO_GPOCFG = 1).
