10 / 126 page General description L9803 10/126 1.2 Pin out Figure 2. Pin out 1.3 Pin Description AD2-AD4: Analog input to ADC. PA0/OCMP2_1-PA1/OCMP1_1: I/Os or Output compares on Timer 1. Alternate function software selectable (by setting OC2E or OC1E in CR2 register: bit 6 or 7 at 0031h). When used as an alternate function, this pin is a push-pull output as requested by Timer 1. Otherwise, this pin is a triggered floating input or a push-pull output. PA2/ICAP2_1-PA3/ICAP1_1: I/Os or Input captures on Timer 1. Before using this I/O as alternate inputs, they must be configured by software in input mode (DDR=0). In this case, these pins are a triggered floating input. Otherwise (I/O function), these pin are triggered floating inputs or push-pull outputs. PA4/EXTCLK_1: PA4 I/O or External Clock on Timer 1. Before using this I/O as alternate input, it must be configured by software in input mode (DDR=0). In this case, this pin is a triggered floating input. Otherwise (I/O function), this pin is a triggered floating input or a push-pull output. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 17 18 19 20 21 22 23 24 29 30 31 32 25 26 27 28 NU NU NU AD3 AD2 PA1/OCMP1_1 PA0/OCMP2_1 TM VDD OSCIN OSCOUT GND NU VBL VBL VBL NU NU NU NU NU PB1/EXTCLK_2 NU NU PWMO PWMI NRESET CAN_H CAN_L GND VDD VB2 VB1 VBR VBR VBR NU NU NU NU |
