Technical information

( 32 / 76 )
It is not possible to control the pullup by the pullup control registers of ports P00 to P57 (possible to
read and write the pullup control registers).
However, as this product has sockets for installing the pullup resistors, it is possible to pull up by
mounting the resistor arrays included with this product. For the positions for installing them, see
Figure 3.3.
