4. The P60 to P67 pins are CMOS large-current ports in the MCU, but in the emulator, they are
normal ports. However, when this user system interface cable is used, a large current of IOL =
10.0 mA (max.) can be output from the ports by changing the P5 jumper setting. Note that when
the jumper is set to the large-current mode, the P60 to P67 pins become output ports.
Terminals 1 and 2 of jumper P5 are closed: Large-current output ports.
To use the external clock on the user system as the system clock
The pins are set to be normal output ports at shipment.
