Legend:
R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-8
BASE<23:15>:
Chip Select x Base Address bits
bit 6-0
Unimplemented:
Read as ‘0’
Note 1:
The value at POR is 0080h for PMCS1BS and 0880h for PMCS2BS.
2:
If the whole PMCS2BS register is written together as 0x0000, then the last EDS address for the Chip
Select 1 will be FFFFFFh. In this case, Chip Select 2 should not be used. PMCS1BS has no such feature.
