PAD9
• 48/64 LQFP: The ACMPO signal of the analog comparator is mapped to this pin when used with the
ACMP function. If the ACMP output is enabled (ACMPC[ACOPE]=1) the I/O state will be forced to
output.
• 48/64/100 LQFP: The ADC analog input channel signal AN9 and the related digital trigger input are
mapped to this pin. The ADC function has no effect on the output state. Refer to NOTE/2-180 for input
buffer control.
• 48/64/100 LQFP: Pin interrupts can be generated if enabled in digital input or output mode.
• Signal priority:
48 LQFP: ACMPO > GPO
64/100 LQFP: GPO
PAD8
• 48/64/100 LQFP: The ADC analog input channel signal AN8 and the related digital trigger input are
mapped to this pin. The ADC function has no effect on the output state. Refer to NOTE/2-180 for input
buffer control.
• 48/64/100 LQFP: Pin interrupts can be generated if enabled in digital input or output mode.
• Signal priority:
48/64/100 LQFP: GPO
1 _{AMP output takes precedence over DACU output on shared pin.}

PAD6
Table 2-17. Port AD Pins AD7-0
• 32 LQFP: The inverting input signal ACMPM of the analog comparator is mapped to this pin when used
with the ACMP function. The ACMP function has no effect on the output state. Refer to NOTE/2-180
for input buffer control.
• Except 20 TSSOP: The ADC analog input channel signal AN7 and the related digital trigger input are
mapped to this pin. The ADC function has no effect on the output state. Refer to NOTE/2-180 for input
buffer control.
• Except 20 TSSOP: Pin interrupts can be generated if enabled in digital input or output mode.
• Signal priority:
Except 20 TSSOP: GPO
• 32 LQFP: The non-inverting input signal ACMPP of the analog comparator is mapped to this pin when
used with the ACMP function. The ACMP function has no effect on the output state. Refer to
NOTE/2-180 for input buffer control.
• Except 20 TSSOP: The ADC analog input channel signal AN6 and the related digital trigger input are
mapped to this pin. The ADC function has no effect on the output state. Refer to NOTE/2-180 for input
buffer control.
• Except 20 TSSOP: Pin interrupts can be generated if enabled in digital input or output mode.
• Signal priority:
Except 20 TSSOP: GPO
