Bill (03.07.2018 11:17, просмотров: 532) ответил sladkoejka на Ваш контроллер использует autovector? Это когда в LJMP инструкции расположенной в таблице векторов стоит адрес новой таблицы векторов, а процессор подменяет младший байт под соответствующий суб-вектор. Т.е. когда приходит прерывание от USB, в LJMPВообще-то, примеры примеры были сделаны для вашего контроллера. Исходный код#include <ioCY7C68013A.h>
#include <intrinsics.h>
typedef unsigned int uint16_t;
typedef signed int int16_t;
volatile char Flags;
#pragma vector = USB_int
