*
* \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().
