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.
Therefore, the timing specifications provided below are valid at
the DPI_P14–1 pins.
Timer WDTH_CAP Timing
The following timing specification applies to Timer0 and
Timer1 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 specifications provided below are
valid at the DPI_P14–1 pins.
