ten into the indirect register, this register must be written before the target indirect register’s address and RWN=0 is written into the RCRB Access
Control register. If data is to be read from the indirect register, the target indirect register’s address and RWN=1 must be written into the RCRB Access
Control register first, then this register will contain the requested data byte.

= 0: No reading or writing operation on the indirect registers.
= 1: An internal indirect register is being accessed. Any new operation on the internal indirect register is not allowed.
= 0: Write the data to the specified indirect register.
= 1: Read the data to the specified indirect register.
These bits specify the address of the indirect register (from 01H to 0FH & from 11H to 1FH) for the microprocessor access.
This register holds the value which will be read from or written into the indirect registers (from 01H to 0FH & from 11H to 1FH). If data is to be writ-
