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 four 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 : unused OCTET 2 : unused OCTET 3 Bit 4-7: unused Bit 0-3: Mask for digital output 8-11 OCTET 4, Bit 0-7: Mask for digital output 0-7 OCTETS 5-8 contain the level (1=HIGH, 0=LOW) which the outputs to be changed should assume: OCTET 5 : unused OCTET 6 : unused OCTET 7 Bit 4-7: unused Bit 0-3: Level of digital output 8-11 OCTET 8 Bit 0-7 : Level of digital output 0-7
