Registers
The MB89930A series 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 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 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) :
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, 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.)
