ST92195C/D - GENERAL DESCRIPTION

Note 1: I²C available on ST92195D devices only.

Table 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 on page 71.

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.

– If port style = Schmitt trigger, selecting CMOS or

TTL input by software has no 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 the WPU 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.
