6.3.4 SPECIAL FUNCTION REGISTERS
The SFRs are registers used by the CPU and periph-
eral modules for controlling the desired operation of the
device. These registers are implemented as static
RAM. SFRs start at the top of data memory (FFFh) and
extend downward to occupy more than the top half of
Bank 15 (F40h to FFFh). Table 6-2, Table 6-3 and
Table 6-4 provide a list of these registers.
The SFRs can be classified into two sets: those
associated with the “core” device functionality (ALU,
Resets and interrupts) and those related to the
peripheral functions. The Reset and Interrupt registers
are described in their corresponding chapters, while the
ALU’s STATUS register is described later in this section.
Registers related to the operation of the peripheral
features are described in the chapter for that peripheral.
The SFRs are typically distributed among the
peripherals whose functions they control. Unused SFR
locations are unimplemented and read as ‘0’s
Note: The SFRs located between EB0h and
F5Fh are not part of the Access Bank.
Either BANKED instructions (using BSR) or
the MOVFF instruction should be used to
access these locations. When program-
ming in MPLAB
®
C18, the compiler will
automatically use the appropriate
addressing mode.

Note 1: This is not a physical register.
2: This register is not available on 28-pin devices.
3: SSPxADD and SSPxMSK share the same address.
4: PMADDRH and PMDOUTH share the same address, and PMADDRL and PMDOUTL share the same address.
PMADDRx is used in Master modes and PMDOUTx is used in Slave modes.
5: Reserved; do not write to this location.
