Register
The MB95120MB series has two types of registers; dedicated registers in the CPU and general-purpose registers
in the memory. The dedicated registers are as follows:
Program counter (PC)
: A 16-bit register to indicate locations where instructions are stored.
Accumulator (A)
: A 16-bit register for temporary storage of arithmetic operations. In the case of
an 8-bit data processing instruction, the lower 1 byte is used.
Temporary accumulator (T)
: A 16-bit register which performs arithmetic operations with the accumulator.
In the case of an 8-bit data processing instruction, the lower 1 byte is used.
Index register (IX)
: A 16-bit register for index modification
Extra pointer (EP)
: A 16-bit pointer to point to a memory address.
Stack pointer (SP)
: A 16-bit register to indicate a stack area.
Program status (PS)
: A 16-bit register for storing a register bank pointer, a direct bank pointer, and
a condition code register
The PS can further be divided into higher 8 bits for use as a register bank pointer (RP) and a direct bank pointer
(DP) and the lower 8 bits for use as a condition code register (CCR) . (Refer to the diagram below.)
