23.3.3.1.11 CMD_COUNT: Counter Command
Command ID number: 0x080B
CMD_COUNT is a radio operation command. In addition to the parameters listed in
command structure contains the fields listed in
Byte Index Field Name
14–15 counter
When starting, the radio CPU decrements the counter field by 1 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, which can
be used in conditional execution to create a loop.
If the operation is started with counter equal to zero, this is an illegal parameter, so the operation ends
with the status ERROR_PAR.
The operation ends by one of the causes listed in
Condition
Finished operation with counter > 0
Finished operation with counter = 0
23.3.3.1.12 CMD_SCH_IMM: Run Immediate Command as Radio Operation
Command ID number: 0x0810
CMD_SCH_IMM is a radio operation command. In addition to the parameters listed in
command structure contains the fields listed in
Byte Index Field Name
14–15
16–19 cmdrVal
20–23 cmdstaVal
When starting, the radio CPU takes the value in cmdrVal and processes it as if it had been written to the
CMDR register. This command may be a pointer to an immediate command, or it may form a direct
command as shown in
The value that would normally have been returned in CMDSTA is written to cmdstaVal. This means that
no command RF_CMD_ACK interrupt is raised. Instead, a COMMAND_DONE interrupt is raised, as for
any other radio operation command.
Depending on the result of the immediate or direct command, the status and result of the radio operation
command is as shown in
CMD_SCH_IMM may run immediate commands as part of a chain of radio operation commands, or to
schedule them in the future. If an immediate or direct command received in the CMDR register is being
processed at the same time that a scheduled CMD_SCH_IMM command starts, the processing of the
scheduled command starts after the other command has finished.
