ICAEN[31:0]:
The four registers of ICAEN[31:0] control the polling of devices attached to
the SCI-PHY/Any-PHY input port.
When operating in master mode (IMASTER input set to logic 1), the
ICAEN[31:0] bits can be used to selectively remove a PHY device from the
polling sequence. Setting a bit of ICAEN[31:0] to logic 0 prevents the S/UNI-
DUPLEX to poll the corresponding device.
When operating in slave mode, the ICAEN[31:0] bits can be used to disable
logical channels. Logical channels are disabled in group of four consecutive
addresses, i.e. setting to logic 0 one or more bits of a four bit nibble of
ICA[31:0] disables all four corresponding logical channels. If a disabled PHY
