Hello libc maintainers,
May I suggest adding to libc an optimization safe access method to the
timers, for example:
typedef volatile int16_t (*pTCNT);
#define TCNT(n) *(pTCNT)(&TCNT ## n) /* e.g., TCNT(3) */
Without this a 100 "tick" delay loop like this would run forever:
int16_t when, time;
when = TCNT3 + 99;
do {
do_something();
time = when - TCNT3;
}
while (time >= 0);
Thanks, Enoch.
