Rung 2:0
Initializes the high-speed counter each time the RRUN mode is entered.
The high-speed counter data area (N7:5 – N7:9) corresponds with the
starting address (source address) of the HSL instruction. The HSC
instruction is disabled each entry into the RRUN mode until the first time
that it is executed as true. (The high preset was ”pegged” on
initialization to prevent a high preset interrupt from occurring during
the initialization process.)
