Wireless LAN Network Interface Controller
26
Track ID: JATR-1076-21 Rev. 1.0
Offset# Bit# Symbol Description
0 15 NO_ENCRYPT No Encryption.
This packet will be sent out without encryption even if Tx encryption is
enabled.
0 14:12 RSVD Reserved.
0 11:0 TPKTSIZE Transmit Packet Size.
This field indicates the number of bytes required to transmit the frame.
4 31 LENGEXT Length Extension.
This bit is used to supplement the Length field (bits 30:16, offset 4). This bit
will be ignored if the TXRATE is set to 1Mbps, 2Mbps, or 5.5Mbps.
4 30:16 Length PLCP Length: The PLCP length field indicates the number of microseconds
required to transmit the frame.
4 15:0 RTSDUR RTS Duration: These bits indicate the RTS frame’s duration field before
transmitting the current frame and will be ignored if the RTSEN bit is set to 0.
8 31:0 TxBuff 32-bit Transmit Buffer Address.
12 31:16 DURATION Time duration to send this packet plus SIFS and ACK
12 15 MIC_CAL Enable MIC calculation.
12 14:12 RSVD Reserved.
12 11:0 Frame_Length Transmit Frame Length.
This field indicates the length in the Tx buffer, in bytes, to be transmitted.
16 31:0 NTDA 32-bit Address of the Next Transmit Descriptor.
20 31:27 RATE_FALL
BACK_LIMIT
Data Rate Auto Fallback Limit.
20 26:23 RTS_RATE_FALL
BACK_LIMIT
RTS/CTS Rate Auto Fallback Limit.
20 22:19 RSVD Reserved.
20 18 PIFS Setting this bit will cause this frame be sent after PIFS
20 17 NO_ACM No admission control procedure.
This packet will be sent out without being restricted by admission control
procedures. For example, the management type frames shall be sent using the
access category AC_VO without being restricted by admission control
procedures.
20 16 RT_DB Lifetime limited by RETRY_LIMIT (RT_DB=0) or DELAY_BOUND
(RT_DB=1).
20 15:8 RETRY_LIMIT Retry Count Limit.
20 7:0 RTSAGC Tx RTS AGC.
24 31 RSVD Reserved.
24 30:29 SPC Short preamble count.
00: 10 bits
01: 12 bits
10: 14 bits
11: 16 bits
24 28 ANTENNA Tx Antenna.
24 27:20 AGC Tx AGC.
24 19:16 RSVD Reserved.
24 15:0 DELAY_BOUND DELAY BOUND
