ST92141 - GENERAL DESCRIPTION

An alternate function can be selected as follows.

AF Inputs:

– AF is selected implicitly by enabling the corre-

sponding peripheral. Exceptions to this are ADC

analog inputs which must be explicitly selected

as AF by software.

AF Outputs or Bidirectional Lines:

– In the case of Outputs or I/Os, AF is selected ex-

plicitly by software.

Example 1: Standard Timer input

AF: STIN, Port: P3.2, I/O Note: Schmitt trigger.

Write the port configuration bits:

P3C2.2=1

P3C1.2=0

P3C0.2=1

or P3C2.2=0

P3C1.2=0

P3C0.2=1

Enable the Standard Timer input by software as

described in the STIM chapter.

Example 2: Standard Timer output

AF: STOUT, Port: P3.3

Write the port configuration bits (for AF output

push-pull):

P3C2.3=0

P3C1.3=1

P3C0.3=1

Example 3: ADC analog input

AF: AIN2, Port: P5.2, I/O Note: does not apply to

analog inputs

Write the port configuration bits:

P5C2.2=1

P5C1.2=1

P5C0.2=1
