PIN DESCRIPTION (Cont’d)
Legend / Abbreviations:
Type:
I = input, O = output, S = supply
Output level: SC = powered by VSC_PWR smartcard power, HS = high sink (on N-buffer only)
Input level:
C = CMOS : 0.3VDD/0.7VDD, SC = CMOS : 0.3VSC_PWR / 0.7VSC_PWR
Port configuration capabilities:
– Input:float = floating, wpu = weak pull-up, int = interrupt, wpd = weak pull-down
– Output: OD = open drain, T = true open drain, PP = push-pull
Note: Reset configuration of each pin is bold.
