Figure 3.8 Position for mounting pullup resistors
3.5 Installing and Removing Pullup Resistors
In this product, you cannot control pullup for ports P0 to P5 by pullup control registers (pullup control
register read/write are possible).
Mounting a pullup resistor inside this product allows pullup control. Mount the 51kΩ resistor array
supplied with this product to the port for which pullup control is required. For the mounting location,
refer to Figure 3.8 below.
CAUTION
Note on Installing and Removing Pullup Resistors:
• Always shut OFF power before installing or removing pullup resistors. Otherwise,
the internal circuits may be damaged.
• Install pullup resistors properly. Otherwise, the emulation pod will be damaged.
