TS
Transmit State. Reports the current transmission state only,
000
RO
no interrupt will be generated.
000: stop
001: read descriptor
010: transmitting
011: FIFO fill, read the data from memory and put into FIFO
100: reserved
101: reserved
110: suspended, unavailable transmit descriptor or FIFO
overflow
111: write descriptor
19~17
RS
Receive State. Reports current receive state only, no interrupt
000
RO
will be generated.
000: stop
001: read descriptor
010: check this packet and pre-fetch next descriptor
011: wait for receiving data
100: suspended
101: write descriptor
110: flush the current FIFO
111: FIFO drain, move data from receiving FIFO into memory

ANISS Added normal interrupt status summary.
1: whenever any of the added normal interrupts occur.
0
RO/LH*

AAISS Added Abnormal Interrupt Status Summary.
1: whenever any of the added abnormal interrupts occur.
0
RO/LH*
14~0
These bits are the same as the status register of CSR5, and
are accessible through either CSR5 or CSR16.
LH* = High Latching and cleared by writing 1.

ANISE Added Normal Interrupt Summary Enable.
0
R/W
1: adds the interrupts of bits 30 and 31 of ACSR7 (CSR17) to
the normal interrupt summary (bit 16 of CSR5).
15
AAIE Added Abnormal Interrupt Summary Enable.
0
R/W
1: adds the interrupt of bits 27, 28, and 29 of ACSR7 (CSR17)
to the abnormal interrupt summary (bit 16 of CSR5).
14~0
These bits are the same as the interrupt enable register of
CSR7, and are accessible through either CSR7 or CSR16.
