7 / 122 page ST7LITE0, ST7SUPERLITE 7/122 PIN DESCRIPTION (Cont’d) Legend / Abbreviations for Table 1: Type: I = input, O = output, S = supply In/Output level: C= CMOS 0.15VDD/0.85VDD with input trigger 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 Table 1. Device Pin Description Note: In the interrupt input column, “eix” defines the associated external interrupt vector. If the weak pull-up col- umn (wpu) is merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input, else the configuration is floating interrupt input.

Caution: During reset, this pin must be held at high level to avoid entering ICC mode unexpectedly (this is guaranteed by the internal pull-up if the application leaves the pin floating). 11 PA5/ ICCDATA I/O CT HS X XX X Port A5 In Circuit Communication Data 12 PA4 I/O CT HS X XX X Port A4 13 PA3 I/O CT HS X XX X Port A3 14 PA2/ATPWM0 I/O CT HS X XX X Port A2 Auto-Reload Timer PWM0 15 PA1 I/O CT HS X XX X Port A1 16 PA0/LTIC I/O CT HS X ei0 X X Port A0 Lite Timer Input Capture 1 |
