Bit
31
Field Name
rdDone
Type
RU
Description
This bit is cleared to 0 by the FW323 when either bit 15 (rdReg) or bit 14 (wrReg)
is set. This bit is set when a register transfer is received from the PHY core.
Reserved.
Bits 30:28 return 0s when read.
This is the address of the register most recently received from the PHY core.
This field is the contents of a PHY core register which has been read.
RWU This bit is set by software to initiate a read request to a PHY core register and is
cleared by hardware when the request has been sent. Bit 14 (wrReg) and bit 15
(rdReg) must be used exclusively.
RWU This bit is set by software to initiate a write request to a PHY core register and is
cleared by hardware when the request has been sent. Bit 14 (wrReg) and bit 15
(rdReg) must be used exclusively.
R
Reserved.
Bits 13:12 return 0s when read.
RW
This field is the address of the PHY core register to be written or read.
RW
This field is the data to be written to a PHY core register and is ignored for reads.
