MPC86X Mode Programmed I/O Access (Synchronous)
If the LIU is interfaced to a MPC86X type P, it should be configured to operate in the MPC86X mode.
MPC86X Read and Write operations are described below.
MPC86X Mode Read Cycle
1.
Place the address of the target register on the address bus input pins ADDR[10:0].
2.
While the P is placing this address value on the address bus, the address decoding circuitry should
assert the CS pin of the LIU, by toggling it "Low". This action enables further communication between the
P and the LIU microprocessor interface block.
3.
Next, the P should indicate that this current bus cycle is a Read operation by pulling the R/W input pin
"High".
4.
The LIU will toggle the TA output pin "Low". The LIU does this in order to inform the P that the data is
available to be read by the P.
5.
After the P detects the TA signal and has read the data, it can terminate the Read Cycle by toggling the
CS input pin "High".
MPC86X Mode Write Cycle
1.
Place the address of the target register on the address bus input pins ADDR[10:0].
2.
While the P is placing this address value on the address bus, the address decoding circuitry should
assert the CS pin of the LIU, by toggling it "Low". This action enables further communication between the
P and the LIU microprocessor interface block.
3.
Next, the P should indicate that this current bus cycle is a Write operation by pulling the R/W input pin
"Low".
4.
Toggle the WE input pin "Low".
5.
After the P toggles the WE signal "Low", the LIU will toggle the TA output pin "Low". The LIU does this in
order to inform the P that the data has been written into the internal register location.
6.
“High”.
