Points to note:
a) It is recommended that the drive input used for the high speed counter functions; HSCS,
HSCR, HSCZ is the special auxiliary RUN contact M8000.
b) If more than one high speed counter function is used for a single counter the selected flag
devices (D) should be kept within 1 group of 8 devices, i.e. Y0-7, M10-17.
c) All high speed counter functions use an interrupt process, hence, all destination devices (D)
are updated immediately.
