2. Register
• Structure of the program status
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:
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.)
Program counter (PC)
Accumulator (A)
Temporary accumulator (T)
Index register (IX)
Extra pointer (EP)
Stack pointer (SP)

: A 16-bit register to indicate locations where instructions are stored.
: A 16-bit register for temporary storage of arithmetic operations. In the case of
: A 16-bit register which performs arithmetic operations with the accumulator.
: A 16-bit register for index modification
: A 16-bit pointer to point to a memory address.
: A 16-bit register to indicate a stack area.
: A 16-bit register for storing a register bank pointer, a direct bank pointer, and
an 8-bit data processing instruction, the lower 1 byte is used.
In the case of an 8-bit data processing instruction, the lower 1 byte is used.
