27.6.1
During reset, the pins for the reset override functions are immediately configured to known states.
Table 27-7
If the RCON pin is not asserted during reset, the chip configuration and the reset configuration pin
functions after reset are determined by the RCON register or fixed defaults, regardless of the states of the
external data pins. The internal configuration signals are driven to levels specified by the RCON register’s
reset state for default module configuration.
If the 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

RCON
CLKMOD1, CLKMOD0
During reset, the CLKMOD pins always determine the clock mode,
regardless of the RCON pin state.
If the external RCON pin is not asserted during reset, pin functions are determined by the
default operation mode defined in the RCON register. If the external RCON pin is asserted, pin
functions are determined by the override values driven on the external data bus pins.
During reset, the external RCON pin assumes its RCON pin function, but this pin changes to
the function defined by the chip operation mode immediately after reset. See
