PA0/AIN0

I/O Port PA0

Analog input to ADC

Alternate function or I/O. The I/O configuration

is software selectable as triggered input or push

pull output. Note that when a pin is used as An-

alog input it must not be configured as an out-

put to avoid conflicts with the analog voltage to

be measured.

PA6/AIN6

I/O Port PA6

PA7/AIN7

I/O Port PA7

PB0/TDO

I/O Port PB0

SCI Transmit Data

Out

Alternate function or I/O. The I/O configuration

is software selectable as triggered input or push

pull output.
