8 / 191 page ST72340, ST72344, ST72345 8/191 PIN DESCRIPTION (Cont’d) For external pin connection guidelines, refer to See “ELECTRICAL CHARACTERISTICS” on page 152. Legend / Abbreviations for Table 1: Type: I = input, O = output, S = supply Input level: A = Dedicated analog input 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 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. On the chip, each I/O port may have up to 8 pads. Pads that are not bonded to external pins are set in in- put pull-up configuration after reset through the option byte Package selection. The configuration of these pads must be kept at reset state to avoid added current consumption. Table 1.
