多路 PWM 输出不同步怎么办？

OPERATE_RET v_ret = OPRT_COM_ERROR;
tkl_pwm_mapping_to_gpio(TUYA_PWM_NUM_0, TUYA_GPIO_NUM_18); // PC2
tkl_pwm_mapping_to_gpio(TUYA_PWM_NUM_1, TUYA_GPIO_NUM_19); // PC3
TUYA_PWM_BASE_CFG_T v_cfg = {
    .duty = 300,
    .frequency = pwm_frequency,
    .polarity = pwm_polarity,
};
tkl_pwm_idle_level_set(TUYA_PWM_NUM_0, 0);
tkl_pwm_idle_level_set(TUYA_PWM_NUM_1, 1);
v_ret = tal_pwm_init(TUYA_PWM_NUM_0, &v_cfg);
v_cfg.polarity = TUYA_PWM_NEGATIVE;
v_ret = tal_pwm_init(TUYA_PWM_NUM_1, &v_cfg);
tal_pwm_start(0xFF);
