2. Registers
The F

MC-8L family has two types of registers; dedicated registers in the CPU and general-purpose registers
in the memory. The following dedicated registers are provided:
Program counter (PC):
A 16-bit register for indicating the instruction storage positions
Accumulator (A):
A 16-bit temporary register for storing arithmetic operations, etc. When the
instruction is an 8-bit data processing instruction, the lower byte is used.
Temporary accumulator (T): A16-bit register which performs arithmetic operations with the accumulator
When the instruction is an 8-bit data processing instruction, the lower byte is used.
Index register (IX):
A16-bit register for index modification
Extra pointer (EP):
A16-bit pointer for indicating a memory address
Stack pointer (SP):
A16-bit register for indicating a stack area
Program status (PS):
A16-bit register for storing a register pointer, a condition code
The PS can further be divided into higher 8 bits for use as a register bank pointer (RP) and the lower 8 bits for
use as a condition code register (CCR). (See the diagram below.)
