Timer PWM_OUT Cycle Timing
The following timing specification applies to timer0 and timer1
in PWM_OUT (pulse-width modulation) mode. Timer signals
are routed to the DPI_P14–1 pins through the DPI SRU. There-
fore, the timing specifications provided below are valid at the
DPI_P14–1 pins.
Table 20. Timer PWM_OUT Timing
Timer WDTH_CAP Timing
The following timing specification applies to timer0 and timer1,
and in WDTH_CAP (pulse width count and capture) mode.
Timer signals are routed to the DPI_P14–1 pins through the
SRU. Therefore, the timing specification provided below is valid
at the DPI_P14–1 pins.
