+ * \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().
