 *
 * \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().
