Lines Matching full:bit
64 Each transmit data chunk begins with a 32-bit data header followed by a
70 chunk consists of a data chunk payload ending with a 32-bit data footer.
176 DNC (Bit 31) - Data-Not-Control flag. This flag specifies the type of SPI
177 transaction. For TX data chunks, this bit shall be ’1’.
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
201 the setting of the DV bit in the data header.
203 SV (Bit 20) - Start Valid flag. The SPI host shall set this bit when the
205 transmit data chunk payload. Otherwise, this bit shall be
206 zero. This bit is not to be confused with the Start-of-Frame
209 SWO (Bit 19..16) - Start Word Offset. When SV = 1, this field shall
210 contain the 32-bit word offset into the transmit data
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
219 chunk payload. Otherwise, this bit shall be zero.
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
277 state of the SYNC bit in the CONFIG0 configuration
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
302 Otherwise, this bit is zero. The SV bit is not to be
306 SWO (Bit 19..16) - Start Word Offset. When SV = 1, this field contains the
307 32-bit word offset into the receive data chunk payload
314 FD (Bit 15) - Frame Drop. When set, this bit indicates that the MAC has
316 received Ethernet frame. This bit is only valid at the end
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
330 64-bit timestamp has been added to the beginning of the
331 received Ethernet frame. The MAC-PHY shall set this bit to
334 RTSP (Bit 6) - Receive Timestamp Parity. Parity bit calculated over the
335 32-bit/64-bit timestamp added to the beginning of the
337 MAC-PHY shall set this bit to zero when RTSA = 0.
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
388 transaction. For control commands, this bit shall be ‘0’.
392 HDRB (Bit 30) - Received Header Bad. When set by the MAC-PHY, indicates
394 host should always clear this bit. The MAC-PHY ignores the
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.
