Line Description
36 to 38 Enables measurement channels.
41 to 42 Sets the high speed ADC, and selects it for all measurement channels.
44 Resets time stamp.
47 to 49 Applies voltage to device, and sets the staircase sweep source.
52 Performs measurement by using the agb1500_sweepMiv function.
55 Sets the specified port to the zero output state.
56 Disables all ports.
39, 45, 50, 53,
and 57
Calls the check_err subprogram (shown in Table 4-1) to check if an error status is
returned for the previous line.
59 to 62 Stops the program execution if the number of returned data is not equal to the nop
value.
