Asserting the external RESET pin for at least four rising CLKOUT edges
causes the external reset request to be recognized and latched.
This active-low output signal is driven low when the internal reset
controller module resets the chip. When RSTOUT is active, the user can
drive override options on the data bus.
The reset controller programming model consists of these registers:
See
description of the registers.
1. S/U = supervisor or user mode access.
2. Writes to reserved address locations have no effect and reads return 0s.
