PIN DESCRIPTION (Cont’d)
Legend / Abbreviations for Table 1:
Type:
I = input, O = output, S = supply
In/Output level: CT= CMOS 0.3VDD/0.7VDD with input trigger
Output level: HS = 20mA high sink (on N-buffer only)
Port and control configuration:
– Input:
float = floating, wpu = weak pull-up, int = interrupt, ana = analog
– Output: OD = open drain, PP = push-pull
The RESET configuration of each pin is shown in bold which is valid as long as the device is in reset state.
