Interrupts
The following timing specification applies to the FLAG0,
FLAG1, and FLAG2 pins when they are configured as IRQ0,
IRQ1, and IRQ2 interrupts as well as the DAI_P20-1 and
DPI_P14-1 pins when they are configured as interrupts.
Table 17. Interrupts
Core Timer
The following timing specification applies to FLAG3 when it is
configured as the core timer (CTIMER).
Table 18. Core Timer
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.
