PIN DESCRIPTION (Cont’d)
Legend / Abbreviations:
Type:
I = input, O = output, S = supply
Input level: A = Dedicated analog input
In/Output 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),
R = 70Ω/100Ω ratio of logical levels.
Analog level if used as PWM filtered with an external capacitor
Port configuration capabilities:
– Input:
float = floating, wpu = weak pull-up, int = interrupt, ana = analog
– Output: OD = open drain, T = true open drain, PP = push-pull
Note: the Reset configuration of each pin is shown in bold.
