Description
Reserved
These bits are always read as 0. Only the initial
values should be written to these bits.
When not specified for CS4, CS5, CS6, CS7,
OE-A*
SDRAMφ* output, setting a PHODR bit to 1 makes
the corresponding pin an NMOS open-drain output
pin, while clearing a PHODR bit to 0 makes the
corresponding pin a CMOS output pin.
