Two 8-bit bidirectional I/O ports P0L and P0H, bit-wise programmable for input or
output via direction bit. Programming an I/O pin as input forces the corresponding
output driver to high impedance state.
In case of an external bus configuration, PORT0 serves as the address (A) and as
the address / data (AD) bus in multiplexed bus modes and as the data (D) bus in
demultiplexed bus modes.

Two 8-bit bidirectional I/O ports P1L and P1H, bit-wise programmable for input or
output via direction bit. Programming an I/O pin as input forces the corresponding
output driver to high impedance state. PORT1 is used as the 16-bit address bus (A)
in demultiplexed bus modes and also after switching from a demultiplexed bus mode
to a multiplexed bus mode.
The following PORT1 pins have alternate functions:

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.
Reset Input with Schmitt-Trigger characteristics. A low level at this pin for a specified
duration while the oscillator is running resets the ST10F269. An internal pull-up
resistor permits power-on reset using only a capacitor connected to V
tional reset mode (enabled by setting bit BDRSTEN in SYSCON register), the
RSTIN line is pulled low for the duration of the internal reset sequence.
Internal Reset Indication Output. This pin is driven to a low level during hardware,
software or watchdog timer reset.
tialization) instruction is executed.
Non-Maskable Interrupt Input. A high to low transition at this pin causes the CPU to
vector to the NMI trap routine. If bit PWDCFG = ‘0’ in SYSCON register, when the
PWRDN (power down) instruction is executed, the NMI pin must be low in order to
force the ST10F269 to go into power down mode. If NMI is high and PWDCFG =’0’,
when PWRDN is executed, the part will continue to run in normal mode.
If not used, pin NMI should be pulled high externally.
