6-bit overflow counter
Load the overflow counter (OVC) with the upper 6 bits of the location pointed
to by the "loc16" addressing mode:
OVC = [loc16(15:10)];
The 6-bit overflow counter is modified.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
