Добрый день.
Не могу получить прерывание от таймера 0.
Хочу чтобы в прерывании ножка ХХ процессора = 1
Вот что я делаю:
NAME main
#define sck_0 =0xffbfff00 //(31-24 bit didect port) 23-16 out, 7-0 input
#define sck_1 =0xff40ff00 //(31-24 bit didect port) 23-16 out, 7-0 input

#define t0ld =0xffff0300
#define t0val =0xffff0304
#define t0con =0xffff0308
#define t0clri =0xffff030c
#define irqen =0xffff0008
