/// \unit
///
/// !Purpose
///
/// Interface for configuration the Pulse Width Modulation Controller (PWM) peripheral.
///
/// !Usage
///
/// -# Configures PWM clocks A & B to run at the given frequencies using
/// PWMC_ConfigureClocks().
/// -# Configure PWMC channel using PWMC_ConfigureChannel(), PWMC_ConfigureChannelExt()
/// PWMC_SetPeriod(), PWMC_SetDutyCycle() and PWMC_SetDeadTime().
/// -# Enable & disable channel using PWMC_EnableChannel() and
/// PWMC_DisableChannel().
/// -# Enable & disable the period interrupt for the given PWM channel using
/// PWMC_EnableChannelIt() and PWMC_DisableChannelIt().
/// -# Enable & disable the selected interrupts sources on a PWMC peripheral
/// using PWMC_EnableIt() and PWMC_DisableIt().
/// -# Control syncronous channel using PWMC_ConfigureSyncChannel(),
/// PWMC_SetSyncChannelUpdatePeriod() and PWMC_SetSyncChannelUpdateUnlock().
/// -# Control PWM override output using PWMC_SetOverrideValue(),
/// PWMC_EnableOverrideOutput() and PWMC_DisableOverrideOutput().
/// -# Send data through the transmitter using PWMC_WriteBuffer().
///
/// Please refer to the list of functions in the #Overview# tab of this unit
/// for more detailed information.
