PIN DESCRIPTION (Cont’d)

Legend / Abbreviations:

Type:

I = Input, O = Output, S = Supply

Input level:

A = Dedicated analog input

Input level:

Output level:

C = CMOS 0.3VDD/0.7VDD,

CT= CMOS 0.3VDD/0.7VDD with input trigger

HS = High Sink (on N-buffer only)

Port configuration capabilities:

– Input:float = floating, wpu = weak pull-up, int = interrupt (\ =falling edge, / =rising edge),

ana = analog

– Output: OD = open drain, T = true open drain (N buffer 8mA@0.4 V), PP = push-pull
