ADC1L和ADC1H老是ff,为啥？
void ADC1_Init()
{
char data SFRPAGE_SAVE = SFRPAGE;
SFRPAGE = 0x00;
AMX0SL=0x00;
SFRPAGE = 0x01;
REF1CN=0x03;
ADC1CF=0x00;
ADC1CN=0x80;
SFRPAGE = SFRPAGE_SAVE;
}
void ADC1_Cover (void)
{
char data SFRPAGE_SAVE = SFRPAGE;
SFRPAGE = 0x01;
Delay_ms(1);
AD1INT = 0;
AD1BUSY = 1;
while (!AD1INT);
result1 = ADC1H;
result2 = ADC1L;
SFRPAGE = SFRPAGE_SAVE;
