Parameter 1: EXT_SIO
Parameter 2: Internal Device
Parameter 3: Numeric Value
Example expression:
IO_WRITE ([p:EXT_SIO], [w:[#INTERNAL]LS0100], 10)
In the above example, 10 bytes of data starting from LS0100 are sent. The following image shows the stored sent data.
The maximum number of transfer bytes when receiving data is 2012.
