XR16V798
6
HIGH PERFORMANCE 2.25V TO 3.6V OCTAL UART WITH FRACTIONAL BAUD RATE
REV. 1.0.1
NOTE: Pin type: I=Input, O=Output, IO= Input/output, OD=Output Open Drain.
RTS7#
36
O
UART channel 7 Request to Send or general purpose output (active LOW). See
description of RTS0# pin.
CTS7#
32
I
UART channel 7 Clear to Send or general purpose input (active LOW). See descrip-
tion of CTS0# pin.
DTR7#
37
O
UART channel 7 Data Terminal Ready or general purpose output (active LOW). See
description of DTR0# pin.
DSR7#
33
I
UART channel 7 Data Set Ready or general purpose input (active LOW). See
description of DSR0# pin.
CD7#
34
I
UART channel 7 Carrier Detect or general purpose input (active LOW).
RI7#
35
I
UART channel 7 Ring Indicator or general purpose input (active LOW).
ANCILLARY SIGNALS
XTAL1
82
I
Crystal or external clock input. Caution: this input is not 5V tolerant.
XTAL2
81
O
Crystal or buffered clock output.
TMRCK
14
I
16-bit timer/counter external clock input.
ENIR
15
I
Infrared mode enable (active HIGH). This pin is sampled during power up, following
a hardware reset (RST#) or soft-reset (register RESET). It can be used to start up all
8 UARTs in the infrared mode. The sampled logic state is transferred to MCR bit-6 in
the UART.
RST#
1
I
Reset (active LOW). The XR16V798 does not have a Power-on reset. Therefore, a
hardware reset must be issued using this pin during power-up. The configuration
and UART registers are reset to default values, see
16/68#
2
I
Intel or Motorola data bus interface select. The Intel bus interface is selected when
this input is HIGH and the Motorola bus interface is selected when this input is LOW.
This input affects the functionality of IOR#, IOW# and CS# pins.
VCC
3,17,28,48,84
+2.25V to 3.6V supply with 5V tolerant serial (modem) inputs.
GND
4,18,29,47,83
Power supply common, ground.
