Reset Controller Module
10.2
Table 10-1
in the following paragraphs.
10.2.1 RESET
Asserting the external RESET for at least four rising CLKOUT edges causes the external reset
request to be recognized and latched.
10.2.2 RSTOUT
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.
10.3
The reset controller programming model consists of these registers:
See
10.3.1 Reset Control Register (RCR)
The RCR allows software control for requesting a reset and for independently asserting the
external RSTOUT pin.

• Reset control register (RCR), which selects reset controller functions
• Reset status register (RSR), which reflects the state of the last reset source
