4.1 Reset Function
A low level on RESET forces all FIFO bits to be cleared. The receive and
transmit FIFO pointers are cleared, which effectively forces the FIFOs to
the empty condition. Since the DSI channels are disabled (ENx = 0), the
DSIxF pins are high and the DSIxS pins are low, which forces the DSI/P
devices to three-state their bus outputs.
Reset also forces all MC68HC55 state machines to their idle state.
