DESCRIPTION

rdDone

Bit 31 is cleared to 0 by the PCI7510 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 layer.

30–28

RSVD

Reserved. Bits 30–28 return 0s when read.

27–24

rdAddr

This field is the address of the register most recently received from the PHY layer.

23–16

rdData

This field is the contents of a PHY register that has been read.

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.

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.

13–12

RSVD

Reserved. Bits 13 and 12 return 0s when read.

11–8

regAddr

This field is the address of the PHY register to be written or read.

7–0

wrData

This field is the data to be written to a PHY register and is ignored for reads.
