27.4.1
If the external RCON pin is asserted during reset, then various chip functions, including the reset
configuration pin functions after reset, are configured according to the levels driven onto the external data
pins. (see
the levels on the external configuration pins to allow for module configuration.
27.4.2
The state of the CLKMOD[1:0] pins during reset determines the clock mode.
