176 DNC (Bit 31) - Data-Not-Control flag. This flag specifies the type of SPI
181 SEQ (Bit 30) - Data Chunk Sequence. This bit is used to indicate an
184 NORX (Bit 29) - No Receive flag. The SPI host may set this bit to prevent
191 RSVD (Bit 28..24) - Reserved: All reserved bits shall be ‘0’.
193 VS (Bit 23..22) - Vendor Specific. These bits are implementation specific.
197 DV (Bit 21) - Data Valid flag. The SPI host uses this bit to indicate
203 SV (Bit 20) - Start Valid flag. The SPI host shall set this bit when the
209 SWO (Bit 19..16) - Start Word Offset. When SV = 1, this field shall
215 RSVD (Bit 15) - Reserved: All reserved bits shall be ‘0’.
217 EV (Bit 14) - End Valid flag. The SPI host shall set this bit when the end
221 EBO (Bit 13..8) - End Byte Offset. When EV = 1, this field shall contain
226 TSC (Bit 7..6) - Timestamp Capture. Request a timestamp capture when the
233 RSVD (Bit 5..1) - Reserved: All reserved bits shall be ‘0’.
235 P (Bit 0) - Parity. Parity bit calculated over the transmit data header.
270 EXST (Bit 31) - Extended Status. This bit is set when any bit in the
273 HDRB (Bit 30) - Received Header Bad. When set, indicates that the MAC-PHY
276 SYNC (Bit 29) - Configuration Synchronized flag. This bit reflects the
284 RCA (Bit 28..24) - Receive Chunks Available. The RCA field indicates to
291 VS (Bit 23..22) - Vendor Specific. These bits are implementation specific.
295 DV (Bit 21) - Data Valid flag. The MAC-PHY uses this bit to indicate
300 SV (Bit 20) - Start Valid flag. The MAC-PHY sets this bit when the current
306 SWO (Bit 19..16) - Start Word Offset. When SV = 1, this field contains the
314 FD (Bit 15) - Frame Drop. When set, this bit indicates that the MAC has
320 EV (Bit 14) - End Valid flag. The MAC-PHY sets this bit when the end of a
324 EBO (Bit 13..8) - End Byte Offset: When EV = 1, this field contains the
329 RTSA (Bit 7) - Receive Timestamp Added. This bit is set when a 32-bit or
334 RTSP (Bit 6) - Receive Timestamp Parity. Parity bit calculated over the
339 TXC (Bit 5..1) - Transmit Credits. This field contains the minimum number
344 P (Bit 0) - Parity. Parity bit calculated over the receive data footer.
387 DNC (Bit 31) - Data-Not-Control flag. This flag specifies the type of SPI
392 HDRB (Bit 30) - Received Header Bad. When set by the MAC-PHY, indicates
397 WNR (Bit 29) - Write-Not-Read. This bit indicates if data is to be written
401 AID (Bit 28) - Address Increment Disable. When clear, the address will be
407 MMS (Bit 27..24) - Memory Map Selector. This field selects the specific
410 ADDR (Bit 23..8) - Address. Address of the first register within the
413 LEN (Bit 7..1) - Length. Specifies the number of registers to read/write.
419 P (Bit 0) - Parity. Parity bit calculated over the control command header.
