23.3.3.1.13 CMD_COUNT_BRANCH: Counter Command With Branch of Command Chain
Command ID number: 0x0812
CMD_COUNT_BRANCH is a radio operation command. In addition to the parameters listed in
the command structure contains the fields listed in
Byte Index Field Name
14–15 counter
16–19 pNextOpIfOk
When starting, the radio CPU decrements the counter field by 1, unless it was already 0, and writes the
result back to this field. If the result of the decrement is zero, the operation ends with the status
DONE_COUNTDOWN and the result FALSE. Otherwise, the operation ends with the status DONE_OK
and the result TRUE. In this case, the next radio operation command to run is given by pNextOpIfOk
instead of pNextOp (see
If the operation is started with the counter equal to zero, the operation ends with the status DONE_OK
and the next operation is taken from pNextOpIfOk. This operation can be used if the previous command is
set up to skip optionally, as skipping from a previous command in the chain follows pNextOp.
The operation ends by one of the causes listed in
Condition
Finished operation with counter = 0 when being started
Finished operation with counter > 0 after decrementing
Finished operation with counter = 0 after decrementing
