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 18H) for the microprocessor access.
This register holds the value which will be read from or written into the indirect registers (from 01H to 18H). If data is to be written into the indirect
