READ
0 = no operation or read complete
1 = read operation is in progress
Setting ‘1’ will initiate read operation. It will be auto cleared if read
operation is completed. Data read from PHY will be stored at
MII_RXDATA (offset = 0x3C)
WRITE
0 = no operation or write complete
1 = write operation is in progress
Setting ‘1’ will initiate write operation. It will be auto cleared if write
operation is completed. Transmit data should be written in
MII_TXDATA (offset = 0x38) before setting this bit.
Scan / setting ‘1’ will initiate a scan operation
0 = no operation or scan complete
1 = SCAN operation is in progress
Scan operation will perform read operation throughout the entire range
of PHY ID and register offsets. Interrupt will be generated (if enabled)
whenever single read is completed. The first PHY ID and register offsets
to start scan operation should be written in bits[12:8] and bits[4:0]
before setting this bit. The CPU needs to clear this bit to stop scan
operation.

PHY address

Register address in a PHY
2.6.2.15. MII_TXDATA (offset = 0x38)
The CPU should write 16-bit TX data prior to send write command via MII_CMD register.
