The PV (content of D2) is compared to the eight SVs in S through S+7 each
time that MTIM(543)/MTIMX(554) is executed, and if any of the SVs is less
than or equal to the PV, the corresponding Completion Flag (D1 bits 00
through 07) is turned ON.
When the PV reaches 9999, the PV will be reset to 0000 and all of the Com-
pletion Flags will be turned OFF. If the reset bit is turned ON while the timer is
operating or paused, the PV will be reset to 0000 and all of the Completion
Flags will be turned OFF.
