8 / 141 page  ST72104Gx, ST72215Gx, ST72216Gx, ST72254Gx 8/141 PIN DESCRIPTION (Cont’d) For external pin connection guidelines, refer to Section 13 "ELECTRICAL CHARACTERISTICS" on page 96. Legend / Abbreviations for Table 1: 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 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 Refer to Section 9 "I/O PORTS" on page 30 for more details on the software configuration of the I/O ports. The RESET configuration of each pin is shown in bold. This configuration is valid as long as the device is in reset state. Table 1.
