During the Connectivity Check the transmitter detects whether the
receiver is connected. The receiver pulses its
to receive data. The transmitter checks for a low pulse on its
ing transmission of its current quad-word.
The Transfer Acknowledge is a handshake for each quad-word transferred.
The receiver drives
quad-word or drives it low to indicate a stall. The transmitter checks for
its
to be high before transmitting the next quad-word.
LxCLKIN
The minimum granularity of the transfer is a quad-word transferred in
eight cycles (16 bytes, on both clock edges). The transfer is initiated by
the transmitter. The transmitter can initiate a transfer only if the receiver
has set its
LxCLKOUT
in receive mode and has a free buffer.
An example for transmit start is shown in Figure 8-4. Note
are shown from the transmitter's point of view. This is also the
LxCLKOUT
case in the figures shown on successive pages, unless otherwise stated.
