Enabling or disabling of the CSn signal is performed by setting
the data direction register (DDR) for the port corresponding to
the particular CSn pin and either the CS167 enable bit
(CS167E) or the CS25 enable bit (CS25E).
In ROM-disabled expansion mode, the CS0 pin is placed in the
output state after a power-on reset. Pins CS1 to CS7 are placed
in the input state after a power-on reset, so the corresponding
DDR bits, and CS167E or CS25E, should be set to 1 when
outputting signals CS1 to CS7.
In ROM-enabled expansion mode, pins CS0 to CS7 are all
placed in the input state after a power-on reset, so the
corresponding DDR bits, and CS167E or CS25E, should be set
to 1 when outputting signals CS0 to CS7.
