  • A cell containing an Event function.
  • A cell containing a Button function.
Start Bit

Specifies the first bit of the set to be read. The value range is 0 – 7, and the default value is 0.
Number of Bits

Specifies the number of bits in the set to be read. The value range is 0 – 8, and the default value is 0.
