7.2.1
This input is driven by an external clock except when used as a connection to the external crystal
when using the internal oscillator.
7.2.2
This output is an internal oscillator connection to the external crystal.
7.2.3
This output reflects the internal bus clock.
7.2.4
The clock mode is selected during reset and reflected in the PLLMODE, PLLSEL, and PLLREF
bits of the synthesizer status. Once reset is exited, the clock mode cannot be changed.
The clock mode selection during reset configuration is summarized in
7.2.5
The RSTOUT pin is asserted by one of the following:
