3.7.3.2 Reset Configuration Register
The reset configuration register (RCON) is a read-only register; writing
to RCON has no effect. At reset, RCON determines the default operation
of certain chip functions. All default functions defined by the RCON
values may be overridden during reset configuration only if the external
RCON pin is asserted.
