os_reset_interval

#include <rtx51tny.h>

void os_reset_interval (
  unsigned char ticks);     /* Number of Timer Ticks */

The os_reset_interval function is used to correct timer problems that occur when the os_wait function is used to wait for K_IVL and K_SIG events simultaneously. In such a case, if a signal (K_SIG) event causes os_wait to exit, the interval timer is not adjusted and subsequent calls to os_wait (to wait for an interval) may not delay for the required time period.

The os_reset_interval routine allows you to reset the interval timer so that subsequent calls to os_wait operate as expected.
