Rung 2:0
Initializes the high-speed counter each time the REM Run 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 REM run 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.)
