PWM Timer疑問
#1

請問
我用Timer3作為PWM Clock的來源
去產生一個9600*16Hz的輸出,工作週期50%
無法正常輸出!!!
但是當我把Clock的來源設成Timer2時,就正常了
也試過其他的Tiemr(除了Timer2),就是無法正常輸出

因為我現在要兩個PWM輸出
且輸出的頻率不同
請問如何解決?!

我用的是PIC24FJ128GA108,Rev 0x1

註:產生的Clock是用來作為外接IrDA Encoder/Decoder Clock用的,在108內無法設定UEN來輸出16xBCLK,但是106可以...囧

謝謝

以下是程式:
static void _section(".oc5") vOC5Init()
{
mIO_UNLOCK();
RPOR1bits.RP2R=22;
mIO_LOCK();

OC5CON1=0x0000;
//OC5CON2=0x0000;

OC5CON1bits.OCTSEL = 0b001;
OC5R =FCY/9600/16/2;
OC5RS = FCY/9600/16/2;

OC5CON1bits.OCM = 0x0006;

IPC10bits.OC5IP0 = 1;
IPC10bits.OC5IP1 = 0;
IPC10bits.OC5IP2 = 0;
IFS2bits.OC5IF = 0;
IEC2bits.OC5IE =0;
//---------------------------

T3CONbits.TON=0;

T3CONbits.TCS=0;

T3CONbits.TCKPS=0;
PR3=FCY/9600/16;

IFS0bits.T3IF=0;
IEC0bits.T3IE=0;

T3CONbits.TON=1;

}
//---------------------------------------------------------
int _section(".main") main(void)
{
vOC2Init();
while(1);
}
