Transmit State. Report the current transmission state only,
no interrupt will be generated.

Receive State. Report current receive state only, no
interrupt will be generated.
000: stop
001: read descriptor
010: check this packet and pre-fetch next descriptor
011: wait for receiving data

Normal Interrupt Status Summary. It’s set if any of below
bits of CSR5 asserted. (Combines with bit 16 of ACSR5)
Abnormal Interrupt Status Summary. It’s set if any of below
bits of CSR5 asserted. (Combines with bit 15 of ACSR5)
Reserved
Fatal Bus Error.
1: while any of parity error, master abort, or target abort is
occurred (see bits 25~23 of CSR5). AN983B will disable all
bus access. The way to recover parity error is by setting
software reset.
