MEMORY ORGANIZATION
PIC16HV540 memory is organized into program mem-
ory and data memory. For devices with more than 512
bytes of program memory, a paging scheme is used.
Program memory pages are accessed using one or two
STATUS register bits. For devices with a data memory
register file of more than 32 registers, a banking
scheme is used. Data memory banks are accessed
using the File Selection Register (FSR).
4.1
Program Memory Organization
The PIC16HV540 has a 9-bit Program Counter (PC)
capable of addressing a 512 x 12 program memory
space (Figure 4-1). Accessing a location above the
physically implemented address will cause a wrap-
around.
The reset vector for the PIC16HV540 is at 1FFh. A
NOP at the reset vector location will cause a restart at
location 000h.

Data Memory Organization
Data memory is composed of registers, or bytes of
RAM. Therefore, data memory for a device is specified
by its register file. The register file is divided into two
functional groups: special function registers and
general purpose registers.
The special function registers include the TMR0 regis-
ter, the Program Counter (PC), the Status Register, the
I/O registers (ports), and the File Select Register
(FSR). In addition, special purpose registers are used
to control the I/O port configuration and prescaler
options.
The general purpose registers are used for data and
control information under command of the instructions.
For the PIC16HV540, the register file is composed of
10 special function registers and 25 general purpose
registers (Figure 4-2).
4.2.1
GENERAL PURPOSE REGISTER FILE
The register file is accessed either directly or indirectly
through the file select register FSR (Section 4.8).

4.2.2
SPECIAL FUNCTION REGISTERS
The Special Function Registers are registers used by
the CPU and peripheral functions to control the opera-
tion of the device (Table 4-1).
The special registers can be classified into two sets.
The special function registers associated with the
“core” functions are described in this section. Those
related to the operation of the peripheral features are
described in the section for each peripheral feature.
