The following Analog peripherals
are exercised:
• ADC1, ADC2
• Comparator 1,
Comparator 2,
Comparator 3,
Comparator 4,
Comparator 5,
Comparator 6
(1) The following is done in a loop:
• Code is running out of RAM.
• All I/O pins are left unconnected.
• All the communication peripherals are exercised in loop-back mode.
• USB – Only logic is exercised by loading and unloading FIFO.
• µDMA does memory-to-memory transfer.
• DMA does memory-to-memory transfer.
• VCU – CRC calculated and checked.
• FPU – Float operations performed.
• ePWM – 6 enabled and generates 150-kHz PWM output on 12 pins, HRPWM clock enabled.
• Timers and Watchdog serviced.
• eCAP in APWM mode generates 36.6-kHz output on 4 pins.
• ADC performs continuous conversion.
• FLASH is continuously read and in active state.
• XCLKOUT is turned off.
