MB89170/170A/170L Series
2. Registers
The F
2
MC-8L family has two types of registers; dedicated hardware registers in the CPU and general-purpose
memory registers. 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 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 which is used for 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 pointer for indicating a stack area
Progam status (PS) :
A 16-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.)
