c8051f360单片机flash擦除问题

EA = 0;
SFRPAGE = 0x00;
VDM0CN |= 0x80;
for (j = 10000; j > 0);
RSTSRC = 0x02;
FLKEY = 0xA5; FLKEY = 0xF1; PSCTL |= 0x03; VDM0CN |= 0x80; for (j = 10000; j > 0; j--); RSTSRC = 0x02; *pwrite = 0; PSCTL = PSCTL &~0x03;对于c8051f360单片机在对flash进行擦除的时候为什么VDM0CN，RSTSRC的值不随着所附的值变化呢？帮忙看看哪里有错误，谢谢！

Answer 1

请问你的i是定义的什么类型呢！估计你是定义的为 unsigned char吧！那就有问题了、unsigned char范围只有0~256而你要加到350、而当i加到255的时候再加一

Answer 2

A = 0;
SFRPAGE = 0x00;
VDM0CN |= 0x80;
for (j = 10000;
