Description

Doc ID 12370 Rev 8

25/324

List of abbreviations used in Table 3

Type:

I = input, O = output, S = supply

In/Output level: CT= CMOS 0.3VDD/0.7VDD with Schmitt trigger

TT= TTL 0.8V / 2V with Schmitt trigger

Output level:

HS = 20mA high sink (on N-buffer only)

Port and control configuration:

Input:

float = floating, wpu = weak pull-up, int = interrupt, ana = analog,

RB = robust

Output:

OD = open drain, PP = push-pull

Refer to Chapter 8: I/O ports for more details on the software configuration of the I/O ports.

The RESET configuration of each pin is shown in bold which is valid as long as the device is

in reset state.
