This HSC instruction is not placed in the high-speed counter interrupt
subroutine. If this instruction were placed in the interrupt
subroutine, the high-speed counter could never be started or
initialized (because an interrupt must first occur in order to scan the
high-speed counter interrupt subroutine).
