Port 4 is a 2-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state.
In case of an external bus configuration, Port 4 can be used to
output the segment address lines:
P4.0
A16
Least Significant Segment Addr. Line
P4.1
A17
Most Significant Segment Addr. Line

XTAL1:
Input to the oscillator amplifier and input to the
internal clock generator
XTAL2:
Output of the oscillator amplifier circuit.
To clock the device from an external source, drive XTAL1,
while leaving XTAL2 unconnected. Minimum and maximum
high/low and rise/fall times specified in the AC Characteristics
must be observed.

External Bus Configuration selection inputs. These pins are
sampled during reset and select either the single chip mode or
one of the four external bus configurations:
BUSACT EBC1

ROMless versions must have pin BUSACT tied to ‘0’.
27
RSTIN
I
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin for a specified duration while the oscillator is running
resets the SAB 80C166W/83C166W. An internal pullup
resistor permits power-on reset using only a capacitor
connected to
V
SS.
28
RSTOUT
O
Internal Reset Indication Output. This pin is set to a low
level when the part is executing either a hardware-, a
software- or a watchdog timer reset. RSTOUT remains low
until the EINIT (end of initialization) instruction is executed.
