SYMBOL DESCRIPTION (* 44 pin LQFP)
-RESET
38
34
32
I
Master Reset (active low). A low on this pin will reset all the
outputs and internal registers. The transmitter output and
the receiver input will be disabled during reset time.

I
Address select lines. To select internal registers.
-IACK
41
37
35
I
Interrupt acknowledge (active low). A low on this pin indicates
that the CPU has received an interrupt. If not used, this pin
should be tied to VCC.
-DACK
10

4
O
Data Transfer Acknowledge ( three-state active low output).
A low on this pin indicates proper transfer of data between
the CPU and XR68C92/192 during read, write and interrupt
cycles.
-CS
39
35
33
I
Chip select (active low). A low at this pin enables the data
bus transfer operation.
D0-D7
28,18

22,12
Bi-directional data bus. Eight bit, three state data bus to

I
Read/Write strobe. When -CS is asserted, a high on this pin
transfers the contents of the XR68C92/192 data bus to the
CPU, and a low on this pin will transfer the contents of the
CPU data bus to the addressed register.
-INT
24
21
18
O
Interrupt output (open drain, active low) This pin goes low
upon occurrence of one or more of eight maskable interrupt
conditions (when enabled by the interrupt mask register).
CPU can read the interrupt status register to determine the
interrupting condition(s). This output requires a 10k ohms
pull-up resistor.
XTAL1
36
32
30
I
Crystal input 1 or external clock input. A crystal can be
connected between this pin and XTAL2 pin to utilize the
internal oscillator circuit. An external clock can be used to
clock internal circuit and baud rate generator for custom
transmission rates.
