C8051F410 读写FLASH

[shoushui2009]

C8051F410单片机，下面是擦Flash的函数代码：
void FLASH_PageErase (FLADDR addr)
{

bit EA_SAVE = EA; // Preserve EA
unsigned char xdata * pwrite; // FLASH write pointer

EA = 0; // Disable interrupts

VDM0CN = 0xA0; // Enable VDD monitor and high threshold

RSTSRC = 0x02; // Enable VDD monitor as a reset source

pwrite =(unsigned char xdata * ) addr;

FLKEY = 0xA5; // Key Sequence 1
FLKEY = 0xF1; // Key Sequence 2
PSCTL |= 0x03; // PSWE = 1; PSEE = 1


VDM0CN = 0xA0; // Enable VDD monitor and high threshold

RSTSRC = 0x02; // Enable VDD monitor as a reset source
*pwrite= 0; // Initiate page erase PSCTL &= 0x00; // PSWE = 0; PSEE = 0
P2=0x02;
EA = EA_SAVE; // Restore interrupts
}
在KEIL 下调试，运行到红色一行代码就暂停了，这是什么原因？

期待解答...

PSCTL &= 0x00; // PSWE = 0; PSEE = 0
这句应该在下一行，没有被注释

有可能程序被你擦掉了

你的程序可以被擦掉了。还怎么运行啊。

32K 程序存储区，不会全都用来存储程序，可以存储非易失性数据
