NOTE

The P55/OSCI/ADC6 pin cannot be applied to OSCI and ADC6 at the same time.

If P55/OSCI/ADC6 functions as OSCI oscillator input pin, then ADE6 bit for R8 must

be ”0” and ADIS2~0 do not select “ 110”. The P55/OSCI/ADC6 pin priority is as follows:

P55/OSCI/ADC6 Pin Priority

High

Medium

Low

OSCI

ADC6

P55

The P70/OSCO/ADC5 pin cannot be applied to OSCO and ADC5 at the same time.

If P70/OSCO/ADC5 acts as OSCO oscillator input pin, then ADE5 bit for R8 must be ”0”

and ADIS2~0 do not select “101”. The P70/OSCO/ADC5 pin priority is as follows:

P70/OSCO/ADC5 Pin Priority

High

Medium

Low

OSCO

ADC5

P70

The P67/IR OUT/ADC4 pin cannot be applied to IR OUT and ADC4 at the same time.

If P67/IR OUT/ADC4 functions as ADC4 analog input pin, then IROUTE bit for IOCA0

must be “0”..

If P67/IR OUT/ADC4 functions as IR OUT analog input pin, then ADE4 bit for R8 must

be ”0” and ADIS2~0 do not select “100”.

The P67/IR OUT/ADC4 pin priority is as follows:

P67/IR OUT/ADC4 Pin Priority

High

Medium

Low

ADC4

IR OUT

P67
