device is doing the following:
- Fetching code from all sectors of IFlash, accessing in read (few fetches) and write to XRAM
- Watchdog Timer is enabled and regularly serviced
- RTC is running with main oscillator clock as reference, generating a tick interrupts every 192 clock cycles
- Four channel of XPWM are running (waves period: 2, 2.5, 3 and 4 CPU clock cycles): no output toggling
- Five General Purpose Timers are running in timer mode with prescaler equal to 8 (T2, T3, T4, T5, T6)
- ADC is in Auto Scan Continuous Conversion mode on all 16 channels of Port5
- All interrupts generated by XPWM, RTC, Timers and ADC are not serviced
