MEMORY ORGANIZATION
There are two memory blocks in PIC16C72 Series
devices. These are the program memory and the data
memory. Each block has its own bus, so that access to
both blocks can occur during the same oscillator cycle.
The data memory can further be broken down into the
general purpose RAM and the Special Function
Registers (SFRs). The operation of the SFRs that
control the “core” are described here. The SFRs used
to control the peripheral modules are described in the
section discussing each individual peripheral module.
Additional information on device memory may be found
in the PICmicro Mid-Range Reference Manual,
DS33023.
2.1
Program Memory Organization
PIC16C72 Series devices have a 13-bit program
counter capable of addressing a 2K x 14 program
memory space. The address range for this program
memory is 0000h - 07FFh. Accessing a location above
the physically implemented address will cause a wrap-
around.
The reset vector is at 0000h and the interrupt vector is
at 0004h.
