Watch Dog Timer Interrupt Mask

When this bit is enabled, a watch dog timer expired interrupt request set in

bit1 of Interrupt Status Register will make AX88180 to issue an interrupt to

host

1 = enable

0 = disable

RXFULIM

R/W

RX Buffer Full Interrupt Mask

When this bit is enabled, a RX buffer full interrupt request set in bit 0 of

Interrupt Status Register will make AX88180 to issue an interrupt to host.

1 = enable

0 = disable

PHYIG

R/W

PHY Interrupt Generation

If this bit is set to ‘1’, it means there is an interrupt request from PHY. AX88180

will forward this interrupt to system. Meantime driver should poll PHY and

adopt proper procedure. Write ‘1’ to this bit to clear this request status.

1 = have interrupt request

0 = no interrupt request

RPIG

R/W

Receive Packet Interrupt Generation

If this bit is set to ‘1’, it means AX88180 receives a packet or (packets) from

PHY. The packet is kept in RX buffer. Write ‘1’ to this bit to clear this request

status.

1 = have received packet

0 = no received packet

FTPI

R/W

Finish Transmitting Packet Interrupt

If this bit is set to ‘1’, it means AX88180 had transmitted packet to PHY. Write

‘1’ to this bit to clear this request status.

1 = finish transmission

0 = none

R/W

WDTEI

R/W

Watch Dog Timer Expired Interrupt

If this bit is set to ‘1’, it means the WATCH DOG timer is expired. AX88180 will

issue an interrupt to host. Write ‘1’ to this bit to clear this request status. The

expired duration can refer to DOGTHD0 and DOGTHD1 registers.

1 = timer expired happens

0 = none

RXFULI

R/W

RX Buffer Full Interrupt

If this bit is set to ‘1’ it means RX buffer is full and no more packets will be

received until packets are read out. Write ‘1’ to this bit to clear this request status.

1 = RX buffer full

0 = None
