Pad types

In the device the following types of pads are available for system pins and functional port

pins:

S = Slow(d)

M = Medium(d) (e)

F = Fast(d) (e)

I = Input only with analog feature(d)

J = Input/Output (‘S’ pad) with analog feature

X = Oscillator

A decoupling capacitor must be placed between each of the three VDD_LV/VSS_LV supply pairs to ensure stable voltage

(see the recommended operating conditions in the device datasheet).

See the I/O pad electrical characteristics in the chip datasheet for details.

All medium and fast pads are in slow configuration by default at reset and can be configured as fast or medium.

The only exception is PC[1] which is in medium configuration by default (see the PCR.SRC description in the

chip reference manual, Pad Configuration Registers (PCR0–PCR148)).
