Functional Description
2.5.6
S-Transceiver Enable / Disable
The layer-1 part of the S-transceiver can be enabled/disabled with the two bits
S_CONF0.DIS_TR and S_CONF2.DIS_TX.
If DIS_TX=’1’ the transmit buffers are disabled. The receiver will monitor for incoming
data in this configuration. By default the transmitter is disabled (DIS_TX = ’1’).
If the transceiver is disabled (DIS_TR = ’1’, DIS_TX = don’t care) all layer-1 functions are
disabled including the level detection circuit of the receiver. In this case the power
consumption of the S-transceiver is reduced to a minimum.
