Bit
Bit Name
20.15 –
20.0
Default
0, RW
Description
TX_PCOM_HI
TX_PCOM_HI:
The high order word of the 32-bit transmitted data field to be used for
out-of-band communications between PHY management entities.
The PHY will send all-0 PCOMs until the high byte has been
accessed.
An access of any of the four TX_PCOM bytes will clear the
TX_PCOM_RDY bit in the ISTAT register.
TX_PCOM Low Register - Register 21
Bit
Bit Name

Default
0, RW
Description
TX_PCOM_LO
TX_PCOM_LO:
The low order word of the 32-bit transmitted data field to be used for
out-of-band communications between PHY management entities.
The PHY will send all-0 PCOMs until the high byte in TX_PCOM_HI
has been accessed.
An access of any of the four TX_PCOM bytes will clear the
