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 (TMREXP).
