Instead of accessing program memory, the User ID’s,
Device ID/Revision ID and Configuration Words can be
accessed when CFGS = 1 in the PMCON1 register.
This is the region that would be pointed to by
PC<15> = 1, but not all addresses are accessible.
Different access may exist for reads and writes. Refer
to
When read access is initiated on an address outside
the
PMDATH:PMDATL register pair is cleared, reading
back ‘0’s.
