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.
