C30 的位元定義要使用位元結構的方式宣告，可以參考它的 p30f5011.h 裡的方法，這種方式是標準的 ANSI C 規則也是基本。
extern volatile unsigned int TRISE __attribute__((__sfr__)); typedef struct tagTRISEBITS { unsigned TRISE0:1; unsigned TRISE1:1; unsigned TRISE2:1; unsigned TRISE3:1; unsigned TRISE4:1; unsigned TRISE5:1; unsigned TRISE6:1; unsigned TRISE7:1; unsigned TRISE8:1; unsigned TRISE9:1; } TRISEBITS; extern volatile TRISEBITS TRISEbits __attribute__((__sfr__)); extern volatile unsigned int PORTE __attribute__((__sfr__)); typedef struct tagPORTEBITS { unsigned RE0:1; unsigned RE1:1; unsigned RE2:1; unsigned RE3:1; unsigned RE4:1; unsigned RE5:1; unsigned RE6:1; unsigned RE7:1; unsigned RE8:1; unsigned RE9:1; } PORTEBITS; extern volatile PORTEBITS PORTEbits __attribute__((__sfr__));

請問PIC30F5011的 bit 要如何宣告
例如 char的宣告 --> unsigned char 變數名稱 可是bit的宣告-->我用 bit 變數名稱 例如-->bit tt; MPLAB IDE 8.10版 Complier後，會出現錯誤！ 請問關於 bit 的宣告，要如何設定！ 謝謝！
