Section 9 I/O Ports
9.4.4
PUCR5 controls the pull-up MOS in bit units of the pins set as the input ports.
9.4.5
The correspondence between the register specification and the port functions is shown below.
P57/SCL pin
[Legend] X: Don't care.
SCL performs the NMOS open-drain output, that enables a direct bus drive.

Description
Reserved
These bits are always read as 0.
Only bits for which PCR5 is cleared are valid. The pull-up
MOS of the corresponding pins enter the on-state when
these bits are set to 1, while they enter the off-state when
these bits are cleared to 0.
