Description

Default

R/W RX2TX_LPBK

1= Rx to Tx loopback mode for debugging

0= Normal mode

(INTR pin of IP101G/IP101GA should pull 5.1K resistor to

DVDD33_IO for normal mode operation. We can connect INTR

pin to GND for Rx to Tx loopback test.)

R/W Reserved

23[11]

R/W FIX_TXD_EN

1= Fix TXD pattern

0= Normal mode

23[10]

R/W FIX_TXD_SEL

1= Long pulse

0= Short pulse

23[9]

R/W FORCE_TX_LPI

1= Force TX LPI

0= TX respond to MII
