This example shows how to program the I2C port.
In the main spreadsheet, select the test (row) and the appropriate tester resource (column).
In this device, the two I/O ports are programmed through the I2C port with the date pattern "5A",
using control code "02". Then the direction is changed to input using control code "06".
Finally, the Read is done, and the expected data is entered into bytes 1 and 2.
(Note this data is NOT sent to the DUT, but is for comparison purposes.)
The tester calculates the first I2C byte (in column 0) and also takes care of the start bit,
stop bits, and acknowledge handshaking automatically. The actual data sent by the DUT
will be compared to the "5A" expected pattern. |
