PIN DESCRIPTION (Cont’d)

Legend / Abbreviations for Table 1:

Type:

I = input, O = output, S = supply

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

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

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