PIC18F87J11 FAMILY
5.3.4.1
In several locations in the SFR bank, a single address
is used to access two different hardware registers. In
these cases, a “legacy” register of the standard PIC18
SFR set (such as OSCCON, T1CON, etc.) shares its
address with an alternate register. These alternate reg-
isters are associated with enhanced configuration
options for peripherals, or with new device features not
included in the standard PIC18 SFR map. A complete
list of shared register addresses and the registers
associated with them is provided in Table 5-4.
Access to the alternate registers is enabled in software
by setting the ADSHR bit in the WDTCON register
(Register 5-3). ADSHR must be manually set or
cleared to access the alternate or legacy registers, as
required. Since the bit remains in a given state until
changed, users should always verify the state of
ADSHR before writing to any of the shared SFR
addresses.

5.3.4.2
In addition to the shared address SFRs, there are
several registers that share the same address in the
SFR space, but are not accessed with the ADSHR bit.
Instead, the register’s definition and use depends on
the operating mode of its associated peripheral. These
registers are:
• SSPxADD and SSPxMSK: These are two
• PMADDRH/L and PMDOUT2H/L: In this case,

separate hardware registers, accessed through a
single SFR address. The operating mode of the
MSSP module determines which register is being
accessed. See Section 19.4.3.4 “7-Bit Address
Masking Mode” for additional details.
these named buffer pairs are actually the same
physical registers. The PMP module’s operating
mode determines what function the registers take
on. See Section 11.1.2 “Data Registers” for
additional details.
