2. Registers
The F2MC-8L family has 2 types of registers; dedicated registers in the CPU and general-purpose registers in
the memory. The following registers are provided :
The PS can further be divided into higher 8-bit for use as a register bank pointer (RP) and the lower 8-bit for
use as a condition code register (CCR) . (See the diagram below.)
Program counter (PC)
: A 16-bit register for indicating 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) : A 16-bit register for performing arithmetic operations with the accumulator.
When the instruction is an 8-bit data processing instruction, the lower byte is used.
Index register (IX)
: A 16-bit register for index modification.
Extra pointer (EP)
: A 16-bit pointer for indicating a memory address.
Stack pointer (SP)
: A 16-bit register for indicating a stack area.
Program status (PS)
: A 16-bit register for storing a register pointer and condition code.
