Pin description
Legend / Abbreviations for Table 3 and Table 4:
Type: I = input, O = output, S = supply
In/Output level:CT = CMOS 0.3VDD/0.7VDD with input trigger
Output level: 10 mA = 10mA high sink (Fn N-buffer only)
25 mA = 25 mA very 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, T = True open drain
The RESET configuration of each pin is shown in bold. This configuration is kept as long as
the device is under reset state.
