1 Flow of data processing
(1) When reading or writing data
1 The host sends a request message (the read/write command) to the GOT.
2 The GOT performs a read/write processing to its virtual devices according to the request from the
host.
3 Upon completion of the processing, the GOT sends a response message (processing result) to
the host.
4 Creating the following objects on the screen allows you to use the data read/written to the virtual
devices:
• Numerical Display that displays data written by the write command
• Numerical Input that is used to input data to be upload to the host
(2) When outputting interrupts
1 Data are written to the virtual devices for interrupt output from the touch switches on the GOT.
2 The GOT sends the written data (interrupt output) to the host.
