Enhanced Three-Speed Ethernet Controllers
Table 15-10 describes the fields of the EDIS register.
Bits Name
0–1 — Reserved
2 BSYDIS Busy disable.
0 Allow eTSEC to report IEVENT[BSY] status and halt buffer descriptor queue if BSY condition occurs.
1 Do not set IEVENT[BSY] and do not halt buffer descriptor queue if BSY condition occurs.
3 EBERRDIS Ethernet controller bus error disable.
0 Allow eTSEC to report IEVENT[EBERR] status and halt buffer descriptor queue if EBERR condition
occurs.
1 Do not set IEVENT[EBERR] and do not halt buffer descriptor queue if EBERR condition occurs.
4–6 — Reserved
7 BABTDIS Babbling transmit error disable.
0 Allow eTSEC to report IEVENT[BABT] status and set the buffer descriptor TR field.
1 Do not set IEVENT[BABT] nor the buffer descriptor TR field.
8 — Reserved
9 TXEDIS Transmit error disable.
0 Allow eTSEC to report IEVENT[TXE] status.
1 Do not set IEVENT[TXE] if TXE condition occurs.
10–12 — Reserved
13 LCDIS Late collision disable.
0 Allow eTSEC to report IEVENT[LC] status, set the buffer descriptor LC field, and halt buffer descriptor
queue if LC condition occurs.
1 Do not set IEVENT[LC] nor the buffer descriptor LC field, and do not halt buffer descriptor queue if
LC condition occurs.
14 CRLDIS Collision retry limit disable.
0 Allow eTSEC to report IEVENT[CRL] status, set the buffer descriptor RL field, and halt buffer
descriptor queue if CRL condition occurs.
1 Do not set IEVENT[CRL] nor the buffer descriptor RL field, and do not halt buffer descriptor queue if
CRL condition occurs.
15 XFUNDIS Transmit FIFO underrun disable.
0 Allow eTSEC to report IEVENT[XFUN] status, set the buffer descriptor UN field, and halt buffer
descriptor queue if XFUN condition occurs.
1 Do not set IEVENT[XFUN] nor the buffer descriptor UN field, and do not halt buffer descriptor queue
if XFUN condition occurs.
16–27 — Reserved
28 FIRDIS Filer invalid result error disable.
0 Allow eTSEC to report IEVENT[FIR] status.
1 Do not set IEVENT[FIR] if eTSEC fails to reach a definite filer result when attempting to file a received
frame, but discard the frame silently.
29 FIQDIS Filed frame to invalid queue error disable.
0 Allow eTSEC to report IEVENT[FIQ] status.
1 Do not set IEVENT[FIQ] if eTSEC attempts to file a received frame to an invalid (disabled) RxBD ring,
but discard the frame silently.
