This variable allows setting of individual digital outputs. The OCTETS are interpreted bit-by-bit, with each bit corresponding to an output. Bit 0 corresponds to the LSB. The first two OCTETS contain the mask which determines which of the outputs are to be set (corresponding bit = 1) and which outputs are to remain unchanged (corresponding bit = 0): OCTET 1, Bit 0-3: Mask for digital outputs 8-11 Bit 4-7: unused OCTET 2, Bit 0-7: Mask for digital outputs 0-7 OCTETS 3 and 4 contain the level (1=HIGH, 0=LOW) which the outputs to be changed should assume: OCTET 3, Bit 0-3: Level of digital outputs 8-11 Bit 4-7: unused OCTET 4, Bit 0-7: Level of digital outputs 0-7
