This is to avoid entering ICC mode unex- pectedly during a reset. In the application, even if the pin is configured as output, any reset will put it back in input pull-up 13 PA5 / ICCDATA I/O CT HS X ei1 XX Port A5 In Circuit Communication Data 14 PA4 I/O CT HS X XX Port A4 15 PA3/ATPWM1 I/O CT HS X ei0 XX Port A3 Auto-Reload Timer PWM1 16 PA2/ATPWM0 I/O CT HS X XX Port A2 Auto-Reload Timer PWM0 17 PA1/ATIC I/O CT HS X XX Port A1 Auto-Reload Timer Input Cap- ture 18 PA0/LTIC I/O CT HS X XX Port A0 Lite Timer Input Capture 19 OSC2 O Resonator oscillator inverter output 20 OSC1/CLKIN I Resonator oscillator inverter input or External clock input Pin No. Pin Name Level Port / Control Main Function (after reset) Alternate Function Input Output 1 |
