Preliminary Technical Data

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.

Core Timer

The following timing specification applies to FLAG3 when it is

configured as the core timer (CTIMER).

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.
