Legend / Abbreviations for Figure 2 and Table 2:

Type:

I = input, O = output, S = supply

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

Output level: 10mA = 10mA high sink (on N-buffer only)

25mA = 25mA very 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, T = True open drain

Refer to “I/O PORTS” on page 25 for more details on the software configuration of the I/O ports.

The RESET configuration of each pin is shown in bold. This configuration is kept as long as the device is

under reset state.
