 * Description:
 *    Pulse Width Modulation (PWM) driver Header File for the LH7A400.
 *      (Direct Current to Direct Current Converter Interface)
 *
 *  The following functions are provided:
 *   pwm0_init(), pwm1_init(),
 *   pwm0_disable(), pwm1_disable(),
 *   pwm0_set_dutycycle(), pwm1_set_dutycycle(),
 *   pwm0_set_clock_prescaler(), pwm1_set_clock_prescaler(),
 *   pwm0_increase_dutycycle(), pwm1_increase_dutycycle()
 *   pwm0_decrease_dutycycle(), pwm1_decrease_dutycycle()
 *   pwm0_increase_clock_prescaler(), pwm1_increase_clock_prescaler()
 *   pwm0_decrease_clock_prescaler(), pwm1_decrease_clock_prescaler()
 *   pwm0_get_duty_cycle_value(), pwm1_get_duty_cycle_value()
 *   pwm0_get_clock_prescaler_value(), pwm1_get_clock_prescaler_value()
 *
 *   Call pwm(x)_init() to initially set both dutycycle and prescaler
 *    for all of the POWER_TYPE register fields.
