Function
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:
P4.0A16Least Significant Segment Addr. Line
P4.1A17Most 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 ob-
served.
External Bus Configuration selection inputs. These pins are sam-
pled during reset and select either the single chip mode or one of
the four external bus configurations:
BUSACTEBC1EBC0Mode/Bus Configuration
00 0 8-bit demultiplexed bus
00 1 8-bit multiplexed bus
01 0 16-bit muliplexed bus
01 1 16-bit demultiplexed bus
10 0 Single chip mode
10 1 Reserved.
11 0 Reserved.
11 1 Reserved.
After reset pin EBC1 accepts the programming voltage for the
Flash Memory as an “alternate function”:
Flash Memory Programming Voltage VPP = 12 V.
Reset Input with Schmitt-Trigger characteristics. A low level at
this pin for a specified duration while the oscillator is running re-
sets the ST10R165. An internal pullup resistor permits power-on
reset using only a capacitor connected to VSS.
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.
