Core Timer
The following timing specification applies to FLAG3 when it is
configured as the core timer (CTIMER).
Table 17. Core Timer
Timer PWM_OUT Cycle Timing
The following timing specification applies to Timer0, Timer1,
and Timer2 in PWM_OUT (pulse-width modulation) mode.
Timer signals are routed to the DAI_P20–1 pins through the
SRU. Therefore, the timing specifications provided below are
valid at the DAI_P20–1 pins.
