IDT82P2282
T1/J1 TPLC Access Status (0C8H, 1C8H)
BUSY:
T1/J1 TPLC Access Control (0C9H, 1C9H)
RWN:
ADDRESS[6:0]:
T1/J1 TPLC Access Data (0CAH, 1CAH)
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 01H to 18H & from 21H to 38H & from 41H to 58H) for the microprocessor access.
This register holds the value which will be read from or written into the indirect registers (from 01H to 18H & from 21H to 38H & from 41H to 58H).
