6. GENERAL REGISTER (GR)
As its name implies, the general register is used for general purposes such as data transfer and operation.
The general register of the 17K series is not a fixed area, but an area specified on the data memory by using
the general register pointer (RP). Therefore, a part of the data memory area can be specified as a general
register as necessary, so that data can be transferred between data memory areas and the data in the data
memory can be operated with a single instruction.
6.1 General Register Pointer (RP)
RP is a pointer that specifies part of the data memory as the general register. RP specifies the bank and
row addresses of a data memory area that is to be specified as the general register. Consisting of a total of
7 bits, RP is assigned to 7DH (RPH) and 7EH (RPL), and the higher 3 bits of the system register (refer to
7.
SYSTEM REGISTER (SYSREG
)
).
RPH specifies a bank, and RPL specifies a data memory row address.
