Enumerations

enum  {
  PWM0 = 0, PWM1 = 1, PWM2 = 2, PWM3 = 3,
  MAX_PWMS = 4
}
 PWM HW block has 4 PWM channels each with its own 10 bit counter. More...
 
enum  PwmClockType { LHL_CLK, PMU_CLK }
 Clock used for PWM. When LHL_CLK is set, 128 KHz is used. When PMU_CLK is set, 1 MHz or 8 MHz. More...
 
enum  { PWM_CHANNEL_MASK = 0x0F }
 
enum  {
  PWM0_OUTPUT_ENABLE_P26 = GPIO_OUTPUT_ENABLE, PWM1_OUTPUT_ENABLE_P27 = GPIO_OUTPUT_ENABLE, PWM2_OUTPUT_ENABLE_P28 = GPIO_OUTPUT_ENABLE, PWM2_OUTPUT_ENABLE_P6 = (GPIO_OUTPUT_ENABLE | (1 << 4)),
  PWM2_OUTPUT_ENABLE_P14 = (2 << 4), PWM3_OUTPUT_ENABLE_P29 = GPIO_OUTPUT_ENABLE, PWM3_OUTPUT_ENABLE_P13 = (2 << 4)
}
