Chip Configuration Module (CCM)
If the RCON pin is not asserted during reset, the chip configuration and the reset configuration pin
functions after reset are determined by RCON 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
on the external configuration pins to allow for module configuration.

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
