• Description: 8-bit Flash-based Microcontroller with A/D Converter and Enhanced Capture/Compare/PWM
• Manufacturer: Microchip Technology

2.0
There are two memory blocks in the PIC16F716
PICmicro
(program memory and data memory) has its own bus
so that concurrent access can occur.
Additional information on device memory may be found
in the PICmicro
(DS33023).
2.1
The PIC16F716 has a 13-bit program counter capable
of addressing an 8K x 14 program memory space. The
PIC16F716 has 2K x 14 words of program memory.
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.

2.2
The data memory is partitioned into multiple banks
which contain the General Purpose Registers (GPR)
and the Special Function Registers (SFR). Bits RP1
and RP0 of the Status register are the bank select bits.
Each bank extends up to 7Fh (128 bytes). The lower
locations of each bank are reserved for the Special
Function Registers. Above the Special Function
Registers
implemented as static RAM. All implemented banks
contain Special Function Registers. The upper 16
bytes of GPR space and some “high use” Special
Function Registers in Bank 0 are mirrored in Bank 1 for
code reduction and quicker access.
