I/O sampling commands

The following commands configure I/O sampling on an originating device. Any I/O sample generated
by this device is sent to the address specified by DH and DL. You must configure at least one I/O line as
an input or output for a sample to be generated.

IS command

Immediately forces an I/O sample to be generated for the digital and analog I/O lines that are
configured for the local device. If you issue the command to the local device, the sample data is sent
out the local serial interface. If sent remotely, the sample is taken on the destination and the sample
data is returned as an
If the device receives ERROR as a response to an IS query, there are no valid I/O lines to sample.

Standard I/O capability
If AO command is set to 2, the XBee3 802.15.4 RF Module's IS I/O options are
command and four analog channels: AD0/DIO0 - AD3/DIO3.
When operating in Transparent mode
the following format:
All bytes are converted to ASCII:
number of samples<CR>
AIO/DIO mask (Bits 0 - 8 are digital I/O; Bits 9 - 12 analog channels)<CR>
DIO data<CR> (If DIO lines are enabled)
ADC channel Data<CR> (This will repeat for every enabled ADC channel)
<CR> (end of data noted by extra <CR>)
When operating in API mode (AP = 1), the command immediately returns an OK response. The data
follows in the normal API format for DIO data.
Extended I/O capability
If A0 is set to 0 or 1, the XBee3 802.15.4 RF Module's IS I/O options are
and P0 command
When operating in Transparent mode (AP = 0 and AO = 0, AO = 1), the data is returned in the following
format:
All bytes are converted to ASCII:
number of samples<CR>
DIO mask (Bits 0 - 14 are digital I/O<CR>
AIO mask (Bits 0 - 3 are Analog channels<CR>
DIO data<CR> (If DIO lines are enabled)
ADC channel Data<CR> (This will repeat for every enabled ADC channel)
<CR> (end of data noted by extra <CR>)
When operating in API mode (AP = 1), the command immediately returns an OK response. The data
follows in the normal API format for DIO data.
