E1 TPLC Access Data (0CAH, 1CAH, 2CAH, 3CAH, 4CAH, 5CAH, 6CAH, 7CAH)
D[7:0]:
If data is to be written into the indirect register, this register must be written before the target indirect register’s address and RWN=0 is written into the
TPLC 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
TPLC 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 00H to 3FH & from 41H to 4FH & from 51H to 5FH) for the microprocessor access.
This register holds the value which will be read from or written into the indirect registers (from 00H to 3FH & from 41H to 4FH & from 51H to 5FH).
