2812源代码，为什么不能生成PWM波？请教达人

#include "DSP28_Device.h" void init_eva(void); void main(void) { InitSysCtrl(); EALLOW; GpioMuxRegs.GPAMUX.all = 0x00FF; // EVA PWM 1-6 pins GpioMuxRegs.GPBMUX.all = 0x00FF; // EVB PWM 7-12 pins EDIS; DINT; InitPieCtrl(); IER = 0x0000; IFR = 0x0000; InitPieVectTable(); init_eva(); for(;;); } void init_eva() { EvaRegs.T1PR = 0xFFFF; // Timer1 period EvaRegs.T1CMPR = 0x3C00; // Timer1 compare EvaRegs.T1CNT = 0x0000; // Timer1 counter EvaRegs.T1CON.all = 0x1042; EvaRegs.T2PR = 0x0FFF; // Timer2 period EvaRegs.T2CMPR = 0x03C0; // Timer2 compare EvaRegs.T2CNT = 0x0000; // Timer2 counter EvaRegs.T2CON.all = 0x1042; EvaRegs.GPTCONA.bit.TCOMPOE = 1; EvaRegs.GPTCONA.bit.T1PIN = 1; EvaRegs.GPTCONA.bit.T2PIN = 2; EvaRegs.CMPR1 = 0x0C00; EvaRegs.CMPR2 = 0x3C00; EvaRegs.CMPR3 = 0xFC00; EvaRegs.ACTR.all = 0x0666; EvaRegs.DBTCONA.all = 0x0000; // Disable deadband EvaRegs.COMCONA.all = 0xA600; } 其实，代码是移植的别人的程序，基本上没做什么改变。不知为什么在引脚用示波器看，没看到矩形波，只是高电平 困扰了好几天了，郁闷~
