2.2.12 IC
The IC (Internally Connected) pin sets the test mode in which the
µ
PD754244 is tested before shipment. Usually,
you should directly connect the IC pin to the VDD pin with as short a wiring length as possible.
If a voltage difference is generated between the IC and VDD pins because the wiring length is too long, or because
external noise is superimposed on the IC pin, your program may not be correctly executed.
Directly connect the IC pin to the VDD pin.
