ENHANCED MID-RANGE CPU
This family of devices contain an enhanced mid-range
8-bit CPU core. The CPU has 49 instructions. Interrupt
capability includes automatic context saving. The
hardware stack is 16 levels deep and has Overflow and
Underflow Reset capability. Direct, Indirect, and
Relative Addressing modes are available. Two File
Select Registers (FSRs) provide the ability to read
program and data memory.
Automatic Interrupt Context Saving
16-level Stack with Overflow and Underflow
File Select Registers
Instruction Set
2.1
Automatic Interrupt Context
Saving
During interrupts, certain registers are automatically
saved in shadow registers and restored when returning
from the interrupt. This saves stack space and user
for more information.
2.2
16-level Stack with Overflow and
Underflow
These devices have an external stack memory 15 bits
wide and 16 words deep. A Stack Overflow or Under-
flow will set the appropriate bit (STKOVF or STKUNF)
in the PCON register, and if enabled will cause a soft-
ware Reset. See Section 3.4 “Stack” for more details.
2.3
File Select Registers
There are two 16-bit File Select Registers (FSR). FSRs
can access all file registers and program memory,
which allows one Data Pointer for all memory. When an
FSR points to program memory, there is one additional
instruction cycle in instructions using INDF to allow the
data to be fetched. General purpose memory can now
also be addressed linearly, providing the ability to
access contiguous data larger than 80 bytes. There are
also new instructions to support the FSRs. See
for more details.
2.4
Instruction Set
There are 49 instructions for the enhanced mid-range
CPU to support the features of the CPU. See
for more
details.
