MCF52233 PWM

冷火团队-小江

放一个关于MCF52233PWM（80-pin)的示例代码：
#include &quotWM.h"
void PWMInit(void)
{
 MCF_GPIO_PTCPAR=0XFF;
 
 MCF_PWM_PWMPRCLK|=MCF_PWM_PWMPRCLK_PCKA(0)|MCF_PWM_PWMPRCLK_PCKB(0);
                 // Configure PWMPRCLK,First time divide Inernal Clock for A,B;Get Clock A,B
 MCF_PWM_PWMSCLA|=MCF_PWM_PWMSCLA_SCALEA(0x80);
                 // Second time divide ,get SA
 MCF_PWM_PWMSCLB|=MCF_PWM_PWMSCLB_SCALEB(0X80);
                 // Second time divide ,get SB
 MCF_PWM_PWMPOL|=MCF_PWM_PWMPOL_PPOL6;
                 // Polarity for PWM6  0:low 1:high
                
 MCF_PWM_PWMCLK|=MCF_PWM_PWMCLK_PCLK6;
                
                // 0:A/B        1:SA/SB
                
 //MCF_PWM_PWMCAE|=MCF_PWM_PWMCAE_CAE6;               
 
               // 0:left-aligned output mode,1:center-aligned output mode
 //MCF_PWM_PWMCTL|=MCF_PWM_PWMCTL_CON23;
             
              //0:separate 8-bit PWMS,1:16-bit
   MCF_PWM_PWMPER6=MCF_PWM_PWMPER_PERIOD(117);
             // Period data
   MCF_PWM_PWMDTY6=MCF_PWM_PWMDTY_DUTY(58);
            // Duty data
   MCF_PWM_PWMCNT6=MCF_PWM_PWMCNT_COUNT(0);       
            //Reset COUNT                     
 
}
void PWMStart(void)
{
 
 MCF_PWM_PWME|=MCF_PWM_PWME_PWME6;
}
