Utility Bus Read Operation
Utility Bus Read Operation
Utility Bus Read Operation
Utility Bus Read Operation
(ALE),Read(READ) and the Address Data bus (Add/Data[7:0]). At the falling edge of ALE, the PHY samples the address phase of the Add/Data[7:0].
The 77010 then floats the Add/Data[7:0] bus. The PHY drives the Add/Data[7:0] bus until rising edge of PHYCS or READ. See Figure 11 below.
Utility Bus Write Operation
Write (WRITE), and the Address Data bus (Add/Data[7:0]). At the falling edge of ALE, the PHY samples the address phase of the Add/Data[7:0]. The
PHY samples the write data byte on the Add/Data[7:0] bus at the rising edge of PHYCS or WRITE. See Figure 12 below.
