PIN DESCRIPTION (Cont’d)
Legend / Abbreviations:
Type:
I = Input, O = Output, S = Supply
Input level:
A = Dedicated analog input
Input level:
C = CMOS 0.3VDD/0.7VDD,
CT= CMOS 0.3VDD/0.7VDD with input trigger
Output level:
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
