Transmit state. Reports the current transmission
state only, 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
Receive state. Reports 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
100: suspended
101: write descriptor
110: flush the current FIFO
111: FIFO drain, move data from receiving FIFO
into memory
Added normal interrupt status summary.
1: whenever any of the added normal interrupts
occur.
Added abnormal interrupt status summary.
1: whenever any of the added abnormal
interrupts occur.
These bits are the same as the status register of
CSR5, and are accessible through either CSR5
or CSR16.
