Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 31-16 Unimplemented: Read as ‘0’

bit 15 CS2: Chip Select 2 bit(1)

1 = Chip Select 2 is active

0 = Chip Select 2 is inactive

bit 15 ADDR<15>: Target Address bit 15(2)

bit 14 CS1: Chip Select 1 bit(3)

1 = Chip Select 1 is active

0 = Chip Select 1 is inactive

bit 14 ADDR<14>: Target Address bit 14(4)

bit 13-0 ADDR<13:0>: Address bits

When the CSF<1:0> bits (PMCON<7:6>) = 10 or 01.

When the CSF<1:0> bits (PMCON<7:6>) = 00.

When the CSF<1:0> bits (PMCON<7:6>) = 10.

When the CSF<1:0> bits (PMCON<7:6>) = 00 or 01.

Note:

If the DUALBUF bit (PMCON<17>) = 0, the bits in this register control both read and write target

addressing. If the DUALBUF bit = 1, the bits in this register are not used. In this instance, use the

PMRADDR register for Read operations and the PMWADDR register for Write operations.
