6.3.4.1 Context Defined SFRs
There are several registers that share the same
address in the SFR space. The register’s definition and
usage depends on the operating mode of its associated
peripheral. These registers are:
• SSPxADD and SSPxMSK: These are two
separate hardware registers, accessed through a
single SFR address. The operating mode of the
MSSP modules determines which register is
being accessed. See Section 19.5.3.4 “7-Bit
Address Masking Mode” for additional details.
• PMADDRH/L and PMDOUT2H/L: In this case,
these named buffer pairs are actually the same
physical registers. The Parallel Master Port (PMP)
module’s operating mode determines what func-
tion the registers take on. See Section 11.1.2
“Data Registers” for additional details.
