The RESET input resets the internal registers and the serial interface outputs in both channels to their default
state (see
Table 16
). An active high pulse of longer than 40 ns duration will be required to activate the reset
function in the device. Following a power-on reset or an external reset, the 654 is software compatible with
previous generation of UARTs, 16C454 and 16C554.

During Motorola Bus Mode (16/68# pin is connected to GND), the package interface pins are configured for
connection with Motorola, and other popular microprocessor bus types. In this mode the 654 decodes two
additional addresses, A3 and A4, to select one of the four UART ports. The A3 and A4 address decode
function is used only when in the Motorola Bus Mode.
