See
Table 12
and
Figure 9
.
Interrupts
The timing specification in
Table 13
and
Figure 10
applies to the
FLAG0, FLAG1, and FLAG2 pins when they are configured as
IRQ0, IRQ1, and IRQ2 interrupts. Also applies to DAI_P20
1
pins when configured as interrupts.
Core Timer
The timing specification in
Table 14
and
Figure 11
applies to
FLAG3 when it is configured as the core timer (CTIMER).

Applies after the power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 100
μ
s while RESET is low, assuming
stable VDD and CLKIN (not including start-up time of external clock oscillator).
