clock handler triggered on the WDT overflow (every msec) on the NMI. this is the system clock Referenced by systime_init(). |
|
subsystem handler for every 2nd msec. this is the pulse of the system (subsystems). sound, motor and lcd driver calls are initiated here. task_switch_handler is called from here as well. Referenced by systime_init(). |
