. The low level is 1.
. The high level is 1.
Type Range
Discrete {1|2}
Discrete {RISE|FALL}
/*Set the instrument to sample data on the falling edge
of the clock in SPI decoding*/
/*The query returns FALL*/
Type Range
Discrete {1|2}
Discrete {LSB|MSB}
/*Set the data endian of the SPI decoding to MSB*/
/*The query returns MSB*/
/*Set the polarity of the SDA data line in SPI
decoding to negative*/
/*The query returns NEG*/
