Legend/abbreviations for Table 2:

Type

I = input

O = output

S = supply

Input level

CT = CMOS 0.3VDD/0.7VDD with Schmitt trigger

TT = refer to the G and H ports characteristics in Section 12.8.1 on page 329

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

Output: OD = open drain, PP = push-pull

Refer to Section 5: Central processing unit on page 37 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 the reset

state.
