| #define TICKS_PER_MS 1 |
Number of ticks per millisecond.
This is (obviously) not 100% consistent with the definition of TICKS_PER_SEC, but it allows for multiplications and divisions to be elided. In any case, timer ticks are not expected to be a precision timing source; for example, the standard BIOS timer is based on an 18.2Hz clock.
