This variable allows setting of individual output. The OCTETS are interpreted bit-by-bit, with each bit corresponding to an output. Bit 0 corresponds to the LSB. The first four OCTETS contain the mask which determines which of the outputs are to be considered (corresponding bit = 1) and which outputs are to ignore (corresponding bit = 0): OCTET 1 : unused OCTET 2 : unused OCTET 3 : unused OCTET 4, Bit 0: Mask for digital outputs 0 OCTETS 5-8 contain the level (1=HIGH, 0=LOW) which the outputs should assume: OCTET 5 : unused OCTET 6 : unused OCTET 7 : unused OCTET 8, Bit 0: Level of digital outputs 0 OCTETS 9-12 are unused.
