Description
Read as zero
Defines whether the pending data bit in outgoing acknowledgment
frames are always set to ‘1’ or controlled by the main FSM and
the address filtering.
0 - Pending data bit is controlled by main FSM and address
filtering
1 - Pending data bit is always ‘1’.
Defines whether TX underflow should be ignored or not.
0 - Normal TX operation. TX underflow is detected and TX is
aborted if underflow occurs
1 - Ignore TX underflow. Transmit the number of bytes given by
the length field.
Defines whether STXON will set bit 14 in the RXENABLE register or
leave it unchanged.
0: Do not affect RXENABLE.
1: Set bit 14 in RXENABLE. Used for backwards compatibility with
CC2420.
