CONFIGURING THE DMA FOR PATTERN MATCH OPERATION
// disable DMA channel 0 interrupts
// clear any existing DMA channel 0 interrupt flag
// enable the DMA controller
// channel off, priority 3, no chaining
// start irq is UART1 RX, pattern match enabled
// pattern value, carriage return
// program the transfer
// transfer destination physical address
// source size is 1 byte
// dst size at most 256 bytes
// one byte per UART transfer request
// clear existing events, disable all interrupts
// enable Block Complete and error interrupts
// clear the DMA channel 0 priority and subpriority
// set IPL 5, subpriority 2
// enable DMA channel 0 interrupt
// turn channel on
