Driver for hardware timers.
USE_US_TIMER
0 (default): Use default /256 prescale for Timer2 1: Use /16 prescale
The following functions depend on Timer2: - NOW() return value, the Timer2 tick count - Software timers - System time
Software timers are driven by Timer2, which by default uses a /256 prescale providing a resolution of 3.2us and a range of 1' 54".
Enabling this setting increases the resolution to 200ns but reduces the maximum software timer to 7" 9.5s.
