Receiver Clock
This input is used as external 16X clock input to the receiver section. Con-
nect the BAUDOUT# pin to this input externally.

O
Baud Rate Generator Output (active low)
This pin provides the 16X clock of the selected data rate from the baud
rate generator. The RCLK pin must be connected externally to BAUD-
OUT# when the receiver is operating at the same data rate.
When the PC mode is selected, the baud rate generator clock output is
internally connected to the RCLK input. This pin then functions as the
LPT-1 printer port decode logic output, see
Table 3
.

I
PC Mode Select (active low)
When this input is at logic 0, it enables the on-board chip select decode
function according to PC ISA bus COM[4:1] and IRQ[4:3] port definitions.
See
Table 3
for details. This pin has an internal 100k
pull-up resistor.

O
Drive Disable Output
This pin goes to a logic 0 whenever the host CPU is reading data from the
650A. It can control the direction of a data bus transceiver between the
CPU and 650A or other logic functions.

I
Reset Input (active high)
A 40 ns minimum active pulse on this pin will reset the internal registers
and all outputs. The UART transmitter output will be held at logic 1, the
receiver input will be ignored and outputs are reset. See UART Reset
