Flow description (2):
<82B7F>：Select the OFF-tone to produce 134Hz signals.
<81101>：Return to the idle mode. Complete the DCS and return to the standby status.
Ex: Rx mode, No Audio tone signal, DCS sub-tone, AUDO sources = DAC1, DAC2 off,
MIC off, DCS tone=01h all are implemented using interrupts (IRQs) in this example and
use 23h bits for the event status (this step can be omitted in practice yet share the same
program code with polling.) When a DCS event interrupt is received, add an additional
command to read the I/O CMD-23h for event status judgment:
