Sample Rate (ATIR)
If multiple samples are wanted during the wake period then IR can be used. This will
provide ST/IR+1 samples. Each sample will be sent separately.
Wake Host
Wake host parameter (ATWH) delays UART and sample data from being initiated until
the timer has expired. This allows the host to wake up before receiving data or a sensor
to power up before an I/O sample is taken.
Digital outputs and special function outputs such as ON_SLEEP and CTS are not affected
by WH. This is to allow these signals to be used to wake up devices.
Note that for deep sleep, both WH must be expired and the module must be associated
before I/O samples are taken.
