8.5.0.3 S4C016 to S4C031: PARITY OF USER OUTPUT GROUPS
These parameters specify whether the output group instruction is
executed with parity check (even parity).
Parity bits are set as the highest level bits of each output group. For
example, if OG#01 is specified with parity and DOUT OG# (1) 2 is
executed, the result will be 00000010 if 2 is binary converted. Since there
will be only one bit (odd) ON at this time, the parity bit (highest level bit)
will be set to ON and 10000010 (130) will be output to OG# (1).
As in the case of a variable such as DOUT OG# (1) B003 parity bits are
added to the contents of the variable data. However, if the contents of the
variable exceed 127, as in the case of DOUT OG# (1) 128, an alarm will
occur. Remains unchanged if no parity check is specified.
