29.3.1
Asserting the external RSTI for at least four rising CLKOUT edges causes the external reset request to be
recognized and latched.
29.3.2
This active-low output signal is driven low when the internal reset controller module resets the chip. When
RSTO is active, the user can drive override options on the data bus.
29.4
The reset controller programming model consists of these registers:
