How to Configure the I/O Ports
To configure the I/O ports, use the information in

– If Input note = Schmitt trigger, selecting CMOS

An alternate function can be selected as follows.

ST92F124/F150/F250 - GENERAL DESCRIPTION
Example 1: SCI-M input
AF: SIN, Port: P5.2. Schmitt Trigger input.
Write the port configuration bits:
P5C2.2=1
P5C1.2=0
P5C0.2 =1
Enable the SCI peripheral by software as de-
scribed in the SCI chapter.
Example 2: SCI-M output
AF: SOUT, Port: P5.3, Push-Pull/OD output.
Write the port configuration bits (for AF OUT PP):
P5C2.3=0
P5C1.3=1
P5C0.3 =1
Example 3: External Memory I/O
AF: A0/D0, Port : P0.0, Input Note: TTL/CMOS in-
put.
Write the port configuration bits:
P0C2.0=1
P0C1.0=1
P0C0.0 =1
Example 4: Analog input
AF: AIN8, Port : 7.0, Analog input.
Write the port configuration bits:
P7C2.0=1
P7C1.0=1
P7C0.0 =1
