PIN DESCRIPTION (Cont’d)
Legend / Abbreviations for Table 2 :
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
TT= TTL 0.8 V / 2 V with Schmitt trigger
Output level: HS = 20 mA high sink (on N-buffer only)
Port and control configuration:
– Input:
float = floating, wpu = weak pull-up, int = interrupt 1), ana = analog
– Output: OD = open drain 2), PP = push-pull
The RESET configuration of each pin is shown in bold. This configuration is valid as long as the device is
in reset state.
