• Bit [4:0] - TRX_CMD
A write access to register bits TRX_CMD initiate a radio transceiver state transition:

Indicates a successful reception of an ACK frame with
frame pending bit set to 1.
Indicates an ACK frame is about to sent in RX_AACK
slotted
operation
SLOTTED_OPERATION (register 0x2C, XAH_XTRL_0).
The microcontroller must pulse pin 11 (SLP_TR) at the next
back-off slot boundary in order to initiate a transmission of
the ACK frame. For details refer to IEEE 802.15.4-2006,
section 7.5.6.4.2.
