2.2.2
The Special Function Registers are registers used by
the CPU and Peripheral Modules for controlling the
desired operation of the device. These registers are
implemented as static RAM. A list of these registers is
given in Table 2-1.
TABLE 2-1
Legend: x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as ’0’,
Note 1: These registers can be addressed from either bank.

2: The upper byte of the program counter is not directly accessible. PCLATH is a holding register for PC<12:8> whose contents
3: A/D not implemented on the PIC16C62B, maintain as ’0’.
4: Other (non power-up) resets include: external reset through MCLR and the Watchdog Timer Reset.
5: The IRP and RP1 bits are reserved. Always maintain these bits clear.
6: On any device reset, these pins are configured as inputs.
7: This is the value that will be in the port output latch.

The Special Function Registers can be classified into
two sets; core (CPU) and peripheral. Those registers
associated with the core functions are described in
detail in this section. Those related to the operation of
the peripheral features are described in detail in the
peripheral feature section.
