two consecutive frames), it is able to check for data errors. If two different
bytes are received the receiver will wait for the receipt of two identical
successive bytes (last look function).
A collision resolution mechanism ( check if another device is trying to
send data during the same time) is implemented in the transmitter. This
is done by looking for the inactive (‘1’) phase of the MX bit and making a
per bit collision check on the transmitted monitor data ( check if transmitted
‘1’s are on DU/DD line; DU/DD line are open drain lines).
Any abort leads to a reset of the IDT821064 command stack, the
device is ready to receive new commands.
To obtain a maximum speed data transfer, the transmitter anticipates
the falling edge of the receivers acknowledgment.
Due to the inherent programming structure, duplex operation is not
possible. It is not allowed to send any data to the IDT821064, while
transmission is active.
Refer to Figure 4 and 5 for more information about monitor handshake
procedure.
The IDT821064 can be controlled very flexibly by commands operating
on registers or RAM via the GCI monitor channel, refer to “Programming
Description” for further details.
