27.5.3.2 Reset Configuration Register (RCON)
At reset, RCON determines the default operation of certain chip functions. All default functions defined
by the RCON values can only be overridden during reset configuration (see
Configuration”) if the external RCON pin is asserted. RCON is a read-only register.
