// port as output
// use GPIO function
// all LEDs off
// enable interrupts
// allow all levels
// init interrupts
// enable I/O Ports
// This feature is not supported by MB91V460A
// For all other devices the I/O Ports must be enabled
// Initialize led port
// Initialize DMAC
// Initialize UART2
// endless loop
