ST92F124/F150/F250 - GENERAL DESCRIPTION
1.4 I/O PORTS
Port 0, Port 1 and Port 9[7:2] provide the external
memory interface. All the ports of the device can
be programmed as Input/Output or in Input mode,
compatible with TTL or CMOS levels (except
where Schmitt Trigger is present). Each bit can be
programmed individually (Refer to the I/O ports
chapter).
Internal Weak Pull-up
As shown in
ment a Weak Pull-up. This means that the pull-up
must be connected externally when the pin is not
used or programmed as bidirectional.
TTL/CMOS Input
For all those port bits where no input schmitt trig-
ger is implemented, it is always possible to pro-
gram the input level as TTL or CMOS compatible
by programming the relevant PxC2.n control bit.
Refer I/O Ports Chapter to the section titled “Input/
Output Bit Configuration”.
Schmitt Trigger Input
Two different kinds of Schmitt Trigger circuitries
are implemented: Standard and High Hysteresis.
Standard Schmitt Trigger is widely used (see

present on ports P4[7:6] and P6[5:4].
All inputs which can be used for detecting interrupt
events have been configured with a “Standard”
Schmitt Trigger, apart from the NMI pin which im-
plements the “High Hysteresis” version. In this
way, all interrupt lines are guaranteed as “edge
sensitive”.
Push-Pull/OD Output
The output buffer can be programmed as push-
pull or open-drain: attention must be paid to the
fact that the open-drain option corresponds only to
a disabling of P-channel MOS transistor of the
buffer itself: it is still present and physically con-
nected to the pin. Consequently it is not possible to
increase the output voltage on the pin over
V
Pure Open-Drain Output
The user can increase the voltage on an I/O pin
over V
sistor is physically absent: this is allowed on all
“Pure Open Drain” pins. In this case, the push-pull
option is not available and any weak pull-up must
be implemented externally.
