PIC16F1579运行4通道独立且独立运行PWM但失败

我试图配置PIC16F1579运行4通道的独立和独立运行PWM。看来，当我改变了一个频道的dutyCouter，它也会影响到其他频道。不确定如果我错过了某处或没有正确配置它。将样本init和设置为dutyCy.U.PoSlice＝GIE；GPSE＝0x55；PPSLoCK＝0xAA；PPsLoopBit。PPsLoCK＝0x00；；/ /解锁PPS//CKPPsBITS；CKPPS= 0x04；//RA4--＆G.EasART:CK//RA4PPSITS。RA4PPS= 0x09；//RA4--＆G.EuSART:CK RB4PPSBIT。RB4PPS= 0x05；//66ppsBist.RB6PPS= 0x03；/pWM3:PWM1OUT RB7PPsBIT.RB7PPS= 0x06；//RB7- &；pWM4:PWM4OUD RA4PPS= 0x09；RXPPS= 0x15；RC5PPS= 0x0A；//RC5PPSITS。RC5PPS= 0x0a；//RC5--Gt；EUSAART：DT PPSROCK＝0x55；PPSROCK＝0xAA；PPS RB4--gt；pWM1:PWM3OUT RB5PPsBI.RB5PPS= 0x04；//RB5--gt；pWM2:PWM2OUT锁比特＝0x01；//锁定PPS Ge=状态；SLRCONB= 0B10000；//清除速率寄存器/OdCONB= 0B11110000；ANSELB＝0x00；//PWM1 PWM1CKCONN＝0x01；/ /来自HFINTOSC W/O预分频器//PWM1PR＝63；//500 kHz＝0.000002＝（PR＋1）*预刻度/32000000 pWM1PR＝63；//500 kHz＝0.000002。=（pr + 1）*预缩放/ 32000000 pWM1pH＝0；pWM1DC＝0；pWM1ITE= 0x00；//没有中断使PWM1Itff＝0x00；//清除中断标志PWM1LDCONN＝0x00；/ /负载PWM1OFCON＝0x00；/ /独立运行模式PWM1CONN＝0x80；//启用，标准PWM模式，有源高输出//PWM2PWM2CLKCON＝0x01；//来自HFINTOSC W/O预分频器PWM2PR＝63；//500 kHz＝0.000002（PR＋1）*预量/32000000 pWM2pH＝0；PWM2DC＝0；PWM2ITEE＝0x00；//没有中断使能PWM2Itf= 0x00；/ /清除中断标志PWM2LDCONN＝0x00；/ /负载武装的PWM2OFCONN＝0x00；/ /NT运行模式PWM2CON＝0x80；//启用，标准PWM模式，有源高输出//PWM3 PWM3CKCONN＝0x01；/ /来自HFINTOSC W/O预分频器PWM3PR＝63；//500 kHz＝0.000002（PR + 1）*预刻度/32000000 pWM3PH＝0；PWM3DC＝0；PWM3OFE＝0；PWM3ITEE＝0x00；/ /没有中断启用PWM3Itf= 0x00；；清除中断标志PWM3LDCONN＝0x00；//负载载波PWM3OFCON＝0x00；/ /独立运行模式PWM3CONC= 0x80；//启用，标准PWM模式，有源高输出//PWM4 PWM4CKCONN＝0x01；/ /来自HFINTOSC W/O预分频器PWM4PR＝63；//500 kHz＝0.000002＝（PR＋1）*预刻度/32000000 pWM4pH＝0；PWM4DC＝0；PWM4OTE＝0；PWM4NETE＝0x00；//没有中断使PWM4ITNF＝0x00；//清除中断标志PWM4LDCONN＝0x00；/ /负载独立的PWM4OFCON＝0x00；/ /独立运行模式PWM4CON= 0x80；//启用，标准PWM模式，活动高输出}空隙IIIIT（{ / /配置输出TrISABIT.tiSISA0=）0；//输出TrISAbIt＝0；//输出TrISaB2＝0；/TrISC00＝0；//输出TISCIST1。TISISC1＝0；//输出TISCcBITS；TISISC2＝0；/LATA0＝0；//输出断开LATABIT。LATA1＝0；//输出关断LATABIT。S.LATC1＝0；//输出断开/ 0 /；输出/ /配置输入TISCcTIs；TrISC3＝1；//输入TISCc4＝1；//输入TISCcTIs:TrISC5＝1；//输入TISCISTITS TRISC6＝1；//输入/ /配置PPS输出TrISBITS.TISBB4＝0；0；//输出TrISB7＝0；//输出RX/TX TrISABIIT.TISISA4＝0；//TX TrISCITS.TrISC5＝1；//RX}/ /改变CyCurdDutyCype的样本[2 ] = MyOut0+MyOut1；PWM3Con＝0x00；/ /禁用pWMPWM3DC= DutyCype [2 ]；/ /更改DCPWM3PR＝63；//500 kHz＝0.000002＝（PR+1）*PRESCale/3200 000 PWM3PH＝0；/pWM1DC＝0；PWM3ITE= 0x00；//没有中断启用PWM3Itff＝0x00；//清除中断标志WM3LDCONC= 0x00；/ /负载ARMMEM3OFCONN＝0x00；/ /独立运行模式激活HypWM3CON＝0x80；//使能，标准PWM模式

    I am trying to configure the PIC16F1579 to run 4 channel of standalone and Independently run PWM. It seem that when I change the DutyCycle of one of the channel, it will affected other channel as well. Not sure if I miss out somewhere or did not configure it properly. Enclosed the sample Init and Setting for the DutyCycle.
