ST92195B - GENERAL DESCRIPTION
1.2.2 I/O Port Styles
Legend:
AF= Alternate Function, BID = Bidirectional, OD = Open Drain
PP = Push-Pull, TTL = TTL Standard Input Levels
How to Read this Table
To configure the I/O ports, use the information in
this table and the Port Bit Configuration Table in
the I/O Ports Chapter of the datasheet.
Port Style
= the hardware characteristics fixed for
each port line.
Inputs:
– If port style = Standard I/O, either TTL or CMOS
input level can be selected by software.
– Ifport style = Schmitt trigger, selecting CMOS or
TTL input by software hasno effect,the input will
always be Schmitt Trigger.
Weak Pull-Up
= This column indicates if a weak
pull-up is present or not.
– If WPU = yes, then the WPU can be enabled/dis-
able by software
– If WPU = no,then enabling theWPU by software
has no effect
Alternate Functions (AF)
= More than one AF
cannot be assigned to an external pin at the same
time:
An alternate function can be selected as follows.
AF Inputs:
– AF is selected implicitly by enabling the corre-
sponding peripheral. Exception to this are ADC
analog inputs which must be explicitly selected
as AF by software.
