MRF24XA
REGISTER 4-9: RXCON2 (MAC RECEIVE CONTROL 2 REGISTER) (CONTINUED)
ADDRESS: 0x16
bit 2
AUTOACKEN: Auto-Acknowledge Enable bit
Setting this bit enables the device to automatically transmit 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, and must be unmodified while RXEN or TXST is
set.
Use ADPTDREN field while receiving and transmitting, and must be unmodified while RXEN or TXST is
set.
