* Detailed Description:
*
*
* This example shows synchronization between FlexPWM, CTU and ADC modules.
* The FlexPWM Submodule 0 is initialized to generate PWM signal, and rising edge
* of PWM B0 signal is used to generate trigger signal for CTU module. The CTU module
* sends two commands to ADCs. Single conversion mode is used, so ADC0 ch0 and ch1
* are sampled. The conversion result is used to modify PWM B0 rising egde position
* and change delay between external trigger and ADC sequence triggering.
*

* Test HW: MPC57xx
* Maskset: 1N65H
* Target : internal_FLASH
* Fsys: 200 MHz PLL with 40 MHz crystal reference
*
* EVB connection:
*
* P8.1 - A[0] .. GPIO output, used to see CTU-ADC ISR period
* P9.1 - B[7] .. ADC0 AN[0] input
* P9.2 - B[8] .. ADC0 AN[1] input
* P16.4 - I[3] .. CTU0 EXT TRG output
* P8.12 - A[11] .. FlexPWM A[0] output
* P8.11 - A[10] .. FlexPWM B[0] output
*
* connect Trimmer J53.1 to P9.1 to change position of PWM B0 rising edge
* connect Trimmer J53.1 to P9.2 to change CTU trigger delay from PWM B0 rising edge
*
* see CTU0 EXT TRG output signal (toggle on each trigger) on P16.4 with respect of PWM signals
