峰绍FT6532T设置pwm输出

// 1. 配置P0.1为Timer3输出
PH_SEL |= 0x02; // PH_SEL[1]=1 (P0.1映射到Timer3)
P0_OE |= 0x02; // P0.1输出使能

// 2. 配置Timer3
TIM3_CR1 = 0x00; // 预分频=0 (24MHz)
TIM3_AR = 1200;
//TIM3_ARRL = 0xB0; // ARR低字节 = 0xB0
//TIM3_ARRH = 0x04; // ARR高字节 = 0x04 (ARR=1200)
TIM3_DR = 600; //50占空比
//TIM3_DRL = 0xD0; // DR低字节 = 0xD0
//TIM3_DRH = 0x02; // DR高字节 = 0x02 (DR=720)
TIM3_CR0 = 0x01; // 边沿对齐PWM模式，向上计数，使能Timer
