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 I
OL
=
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.
