MRF24XA_15 Datasheet, PDF (40/258 Pages) Microchip Technology – Low-Power, 2.4 GHz ISM-Band IEEE 802.15.4™ RF

MRF24XA
REGISTER 2-21: RXCON2 (MAC RECEIVE CONTROL 2 REGISTER) (CONTINUED)
ADDRESS: 0x16
bit 5
ACKRXFP: ACK RX Frame Pending bit
This read-only Status bit reflects the value of the FrameCtrl (FramePend) bit in the last received 802.15.4
compatible ACK frame.
bit 4
ACKTXFP: ACK TX Frame Pending bit
The value of this bit is transmitted in the FrameCtrl (FramePend) bit slot when the MAC sends out an
ACK packet in 802.15.4 Compatibility mode.
bit 3
AUTORPTEN: Auto-Repeat Enable bit
If this bit is set, the MAC automatically transmits a packet whenever a packet is received, and its Repeat
bit is set.
1 = Auto-Repeat feature is enabled
0 = Auto-Repeat feature is disabled
bit 2
AUTOACKEN: Auto-Acknowledge Enable bit
If this bit is set, then the device automatically transmits an ACK packet whenever a packet is received,
and its AckReq bit is set.
1 = Automatic Acknowledge processing enabled
0 = Automatic Acknowledge processing disabled
bit 1
ADPTCHEN: Adaptive Channel Enable bit⁽¹⁾
Setting this bit enables the MAC in Proprietary mode to set the transmitting channel for the ACK packet
based on the AckInfo field (Proprietary packet) of the received packet, rather than the CH<3:0> register
bits.
1 = Adaptive Channel feature is enabled
0 = Adaptive Channel feature is disabled
This feature is also known as Channel Agility. For more information, see Section 7.1 “Channel Agility”.
bit 0
ADPTDREN: Adaptive Data Rate Enable bit⁽²⁾
Setting this bit enables the MAC in Proprietary mode to set the transmission data rate for the ACK packet
based on the AckInfo field (Proprietary packet) of the received packet, rather than the DR<2:0> register
bits.
1 = Adaptive Data Rate feature is enabled
0 = Adaptive Data Rate feature is disabled
This feature is also known as Channel Agility. For more information, see Section 7.1 “Channel Agility”.
Note 1:
2:
Use ADPTCHEN field while receiving and transmitting a packet, and must be unmodified while RXEN or
TXST is set.
Use ADPTDREN field while receiving and transmitting a packet, and must be unmodified while RXEN or
TXST is set.
