DESCRIPTION
31
rdDone
RU
Bit 31 is cleared to 0 by the TSB82AA2 device when either bit 15 (rdReg) or bit 14 (wrReg) is set to
1. This bit is set to 1 when a register transfer is received from the PHY device.
3028
RSVD
R
Reserved. Bits 3028 return 0s when read.
2724
rdAddr
RU
This field is the address of the register most recently received from the PHY device.
2316
rdData
RU
This field is the contents of a PHY register that has been read.
15
rdReg
RWU
Bit 15 is set to 1 by software to initiate a read request to a PHY register, and is cleared by hardware
when the request has been sent. Bits 14 (wrReg) and 15 (rdReg) must not both be set to 1
simultaneously.
14
wrReg
RWU
Bit 14 is set to 1 by software to initiate a write request to a PHY register, and is cleared by hardware
when the request has been sent. Bits 14 (wrReg) and 15 (rdReg) must not both be set to 1
simultaneously.
1312
RSVD
R
Reserved. Bits 1312 return 0s when read.
118
regAddr
R/W
This field is the address of the PHY register to be written or read.
70
wrData
R/W
This field is the data to be written to a PHY register and is ignored for reads.
