Nothing is assigned. In an attempt to write to this bit, write “0”. The value, if
read, turns out to be indeterminate.
PU01
P44 to P47 pull-up
The corresponding port is pulled
high with a pull-up resistor
0 : Not pulled high
1 : Pulled high
Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be
indeterminate.
