ST7LITEUSx PIN DESCRIPTION
(Cont’d) Port and control configuration:
Legend / Abbreviations for
Table 1: – Input:float = floating, wpu = weak pull-up, int = in- Type: I = input, O = output, S = supply terrupt, ana = analog In/Output level: C – Output: OD = open drain, PP = push-pull T= CMOS 0.3VDD/0.7VDD with input trigger The RESET configuration of each pin is shown in Output level: HS = High sink (on N-buffer only) bold which is valid as long as the device is in reset state.
