HIGH PERFORMANCE DUART WITH 64-BYTE FIFO AND POWERSAVE FEATURE
REV. 1.0.1
Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain.
16/68#
24
I
Intel or Motorola Bus Select.
When 16/68# pin is HIGH, 16 or Intel Mode, the device will operate in the Intel bus
type of interface.
When 16/68# pin is LOW, 68 or Motorola mode, the device will operate in the Motor-
ola bus type of interface.
CLKSEL
25
I
Baud-Rate-Generator Input Clock Prescaler Select for channel A and B. This input is
only sampled during power up or a reset. Connect to VCC for divide by 1 and GND
for divide by 4. MCR[7] can override the state of this pin following a reset or initializa-
tion. See MCR bit-7 and
Figure 5 in the Baud Rate Generator section.
HDCNTL#
37
I
Auto RS-485 half-duplex direction output enable for channel A and B (active low).
Connect this pin to VCC for normal RTS# A/B function and to GND for auto RS-485
half-duplex direction output via the RTS# A/B pins. RTS# output goes low for transmit
and high for receive (polarity inversion is available via EMSR[3]). FCTR[3] in channel
A and B have control only if this input is disabled or at VCC.
RESET
(RESET#)
36
I
When 16/68# pin is HIGH for Intel bus interface, this input becomes RESET (active
high). When 16/68# pin is LOW for Motorola bus interface, this input becomes
RESET# (active low).
A 40 ns minimum active pulse on this pin will reset the internal registers and all out-
puts of channel A and B. The UART transmitter output will be held HIGH, the receiver
input will be ignored and outputs are reset during reset period (see Table 17).
VCC
42
Pwr
2.25V to 3.6V power supply. All input pins, except XTAL1, are 5V tolerant.
GND
17
Pwr
Power supply common, ground.
