Preliminary Technical Data
Reset
Interrupts
The following timing specification applies to the FLAG0,
FLAG1, and FLAG2 pins when they are configured as IRQ0,
IRQ1, and IRQ2 interrupts.

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).
