)

This function configures the L3 and L4_PER system clocks. It also configures the system clocks for the specified ePWMSS instance.

Parameters

pwmss_id

The instance number of ePWMSS whose system clocks have to be configured.

'pwmss_id' can take one of the following values: (0 <= pwmss_id <= 2)

Returns

True if successful False if Unsuccessful
