procedures set the register bits to TRAC_STATUS = 7 (INVALID) when it is started. Not
all status values are used in both RX_AACK and TX_ARET transactions. In TX_ARET
the status SUCCESS_DATA_PENDING indicates a successful reception of an ACK
frame
with
frame
pending
bit
set
to
1.
In
RX_AACK
the
status
SUCCESS_WAIT_FOR_ACK indicates an ACK frame is about to sent in RX_AACK
slotted acknowledgment. Slotted acknowledgment operation must be enabled with the
SLOTTED_OPERATION bit of register XAH_CTRL_0. The application software must
set the SLPTR bit of register TRXPWR 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,
chapter 5.5.4.1. Values not listed in the following table are reserved.

Bit 4:0 – TRX_CMD4:0 - State Control Command
A write access to register bits TRX_CMD initiates a state transition of the radio
transceiver towards the new state as defined by the write access. Do not try to initiate a
further
state
change
while
the
radio
transceiver
is
in
STATE_TRANSITION_IN_PROGRESS
state
(see
TRX_STATUS
register).
FORCE_PLL_ON
is
not
valid
for
the
SLEEP
state
as
well
as
during
STATE_TRANSITION_IN_PROGRESS towards the SLEEP state. Values not listed in
the following table are reserved and mapped to NOP.
