PLADIN
0xFFFF0B4C
0x00000000
Read/write
PLADIN is a data input MMR for PLA.
PLADOUT
0xFFFF0B50
0x00000000
Read
PLADOUT is a data output MMR for PLA.
This register is always updated.
PLALCK
0xFFFF0B54
0x00
Write
PLALCK is a PLA lock option. Bit 0 is written
only once. When set, it does not allow
modifying any of the PLA MMRs, except
PLADIN. A PLA tool is provided in the
development system to easily configure the
PLA.
