MB89670/A Series
The following general-purpose registers are provided:
General-purpose registers: An 8-bit register for storing data
The general-purpose registers are 8 bits and located in the register banks of the memory. One bank contains
eight registers and up to a total of 32 banks can be used on the MB89677A. On the MB89673, there are 16
banks in internal RAM. The remaining 16 banks can be extended externally by allocating an external RAM to
addresses 0180
H
to 01FF
H
using an external circuit. The bank currently in use is indicated by the register bank
pointer (RP).
Note: The number of register banks that can be used varies with the RAM size.
