| | 120 | |
| | 121 | || 0 || '''Tx PHY Active''': asserts when the Tx PHY begins transmitting a frame and de-asserts after the last sample is transmitted || |
| | 122 | || 1 || '''OFDM Rx PHY Active''': asserts when the first FFT is started and de-asserts when the Rx PHY completes processing || |
| | 123 | || 2 || '''DSSS Rx PHY Active''': asserts when the DSSS receiver is processing a frame || |
| | 124 | || 3 || '''OFDM Packet Detect''': asserts when the OFDM Rx PHY attempts a reception. A packet detection event does not always result in an Rx PHY active event || |
| | 125 | || 4 || '''DSSS Packet Detect''': asserts when the DSSS Rx PHY attempts a reception. A packet detection event does not always result in an Rx PHY active event || |
| | 126 | || 5 || '''LTS Timeout''': asserts briefly when the Rx PHY fails to correlate the preamble LTS following a packet detection event || |
| | 127 | || 6 || '''FCS Good''': asserts briefly after the PHY writes the last byte of a received frame to the packet buffer and the checksum calculation indicates no errors || |
| | 128 | || 7 || '''RSSI Det''': asserts when the instantaneous RSSI exceeds a programmed threshold (debug only - does not indicate actual PHY state) || |
| | 129 | || 8 || '''Tx Pending''': asserted by the MAC hardware when a new Tx MPDU is provided by the MAC but has not yet been submitted to the Tx PHY || |
| | 130 | || 9 || '''Idle for DIFS''': asserted whenever the MAC observes the medium has been idle longer than DIFS interval || |
| | 131 | || 10 || '''Backoff Active''': asserted whenever the MAC is deferring to a busy medium; the MAC will not transmit when backing off || |
| | 132 | || 11 || '''NAV Active''': asserted whenever the MAC is enforcing backoff due to virtual carrier sense after reception of a frame with a valid duration field || |
| | 133 | || 12:14 || '''Sw Debug''': General debug outputs controlled by software via a register in the Rx PHY; useful for unobtrusively measuring software execution times || |
| | 134 | || 15 || '''INPUT: Rx OFDM Ext Pkt Det''': input to PHY pkt detect logic which forces a pkt det event, independent of the normal detection thresholds; useful for assuring the Rx PHY attempts reception of every packet transmitted by another node (Tx PHY Active -> Ext Pkt Det is "perfect" packet detection) || |
