现象：触摸按键功能正常，根据案例增加 休眠部分
{ TSCHEN1 = 0xff; //TK0~TK7 仅仅允许K0唤醒
TSCHEN2 = 0x0f; //TK8~TK15
TSCTRL = (1<<3) + (1<<2) + 0; //关闭触摸模块， 允许16位数字比较器, 允许低功耗唤醒。 B7: TSGO, B6: SINGLE, B5: TSWAIT, B4: TSWUCS, B3: TSDCEN, B2: TSWUEN, B1 B0: TSSAMP
NOP(2);
PCON |= 0x02; //睡眠
NOP(5);
PrintString1("STC8H4K64TLR 唤醒后\r\n");
TSCHEN1 = 0xff; //TK0~TK7 允许所有16个键
TSCHEN2 = 0x0f; //TK8~TK15
TSCTRL = (1<<7) + (1<<3) + (1<<2) + 0;}
就无法唤醒了，
扫描函数如下，
void Touch_Init(void)
{
// u8 i;
// TSRT = 0x00; //没有LED分时扫描
TSCHEN1 = 0xff; //TK0~TK7
TSCHEN2 = 0x0f; //TK8~TK12 1111
TSCFG1 = (7<<4) + 6; //开关电容工作频率 = fosc/(2*(TSCFG1[6:4]+1)), 放电时间(系统时钟周期数) 0(125) 1(250) 2(500) 3(1000) 4(2000) 5(2500) 6(5000) 7(7500) 最小3
TSCFG2 = 1; //配置触摸按键控制器的内部参考电压(AVCC的分压比), 0(1/4) 1(1/2) 2(5/8) 3(3/4)
// TSCTRL = (1<<7) + (1<<6) +3; //开始扫描, B7: TSGO, B6: SINGLE, B5: TSWAIT, B4: TSWUCS, B3: TSDCEN, B2: TSWUEN, B1 B0: TSSAMP
TSRT = 0x00; //没有LED分时扫描
TSCTRL =0xa0; //0xa0
//B7:TSGO=1使能触摸按键 1011 0100
//B6:SINGLE=1单次扫描模式、=0自动重复扫描
//B5:TSWAIT=1完成一轮扫描后、TSIF 被硬件置 1，此时触摸按键控制器会暂停扫描，直到 TSIF 标志位被清 0后才开始下一轮的扫描
//B4:TSWUCS=0使用内部32K晶振
//B3:TSDCEN=0不使能16位比较器
//B2:TSWUEN=1使能低功耗唤醒功能
//B1B0:TSSAMP=11单次按键扫描4次
TSWUTC = 20; //唤醒
IE2 |= 0x80; //允许触摸按键中断
EA = 1;
ReadZeroData();
}
