2.2.3 Installing an MCU on the KXICS

Either of two types of MCUs may be installed on the KXICS board, a DIP-type

or a SOIC-type.

2.2.3.1 DIP-type MCU

1. Place the pin tension arm of the KXICS DIP socket XU1 in the up

position.

2. Install the DIP type MCU into the DIP socket XU1. Be sure that the

pin 1 orientation of the silkscreened dot on the MCU aligns with the

pin 1 location on the DIP socket (upper left pin of the socket).
