For data areas IR, SR, LR, HR, and AR, the “Operand” parameter indicates the
data area where the bit will be force-set and the “Word address” parameter indi-
cates the word address.
For the TC area, “Operand” parameter indicates the mnemonic of the timer or
counter instruction and the “Word address” parameter indicates the TC number.

The 16 bytes of forced set/reset/cancel data specifies what operation will be per-
formed on the specified data area word or Completion Flag. If a timer or counter
is specified, the status of the Completion Flag is force-set or force-reset using
the setting for bit 15, and the settings for bits 00 through 14 will be ignored. Only
force-setting and force-resetting are possible for timers/counters.
