| * \par Purpose | |
| * | |
| * Interface for configuration the Pulse Width Modulation Controller (PWM) peripheral. | |
| * | |
| * \par Usage | |
| * | |
| * -# Configures PWM clocks A & B to run at the given frequencies using | |
| * \ref PWMC_ConfigureClocks(). | |
| * -# Configure PWMC channel using \ref PWMC_ConfigureChannel(), \ref PWMC_ConfigureChannelExt() | |
| * \ref PWMC_SetPeriod(), \ref PWMC_SetDutyCycle() and \ref PWMC_SetDeadTime(). | |
| * -# Enable & disable channel using \ref PWMC_EnableChannel() and | |
| * \ref PWMC_DisableChannel(). | |
| * -# Enable & disable the period interrupt for the given PWM channel using | |
| * \ref PWMC_EnableChannelIt() and \ref PWMC_DisableChannelIt(). | |
| * -# Enable & disable the selected interrupts sources on a PWMC peripheral | |
| * using \ref PWMC_EnableIt() and \ref PWMC_DisableIt(). | |
| * -# Control syncronous channel using \ref PWMC_ConfigureSyncChannel(), | |
| * \ref PWMC_SetSyncChannelUpdatePeriod() and \ref PWMC_SetSyncChannelUpdateUnlock(). | |
| * -# Control PWM override output using \ref PWMC_SetOverrideValue(), | |
| * \ref PWMC_EnableOverrideOutput() and \ref PWMC_DisableOverrideOutput(). | |
| * -# Send data through the transmitter using \ref PWMC_WriteBuffer(). | |
