P40 to P43 pull-up
P44 to P47 pull-up
P50 to P53 pull-up
P54 to P57 pull-up
The corresponding port is pulled
high with a pull-up resistor
0 : Not pulled high
1 : Pulled high

P60 to P63 pull-up
PU15
P67 pull-up(Note 2)
PU16
P72 and P73 pull-up (Note 1)
PU17
P74 to P77 pull-up
Notes 1: Since P70 and P71 are N-channel open drain ports, pull-up is not available for them.
2: Pull-up is not available for P6 7 and P72, when they are used as I ²C bus interface ports.
3: When the VCC level is being impressed to the CNV SS terminal, the reset value of this
register becomes to 02 16 (PU11 becomes to “1”).

Nothing is assigned.
In an attempt to write to these bits, write “0.”
The value, if read, turns out to be “0.”
