********************************************************************************
* Detailed Description:
* A simple example configures eTPU engine B channels 0/1 for QOM and FPM.
* Connect these pins by wire. Output wave is generated on chnl ETPUB0 (QOM0)
* and its frequency is measured on the chnl ETPUB1 (FPM0).
* TCR counter frequency is 64MHz, output wave configured as 1MHz ( expected
* frequency measured by FPM. Window size is 28us (0x400) thus number of
* measured pulses is 28 (27 initally).
*
* Note: It is needed to configure IGF module, otherwise inputs does not pass
* to eTPU module.
