The given example is a transfer of an ASCII animation stored in internal flash to the USART_0 output (57600 bps/8 data bits/no parity bit/1 stop bit/no flow control)

This example uses the USART, GPIO, INTC and PDCA modules.

The PDCA interrupt handler.

The handler reload the PDCA settings with the correct ASCII animation address and size using the reload register. The interrupt will happen each time half of the animation is played.Init interrupt controller and register pdca_int_handler interrupt.
