3. KEY MATRIX
SC9243 enables the maximum setting of up to 32 keys through a combination of KI0 to KI7 and KO0~KO3.
Furthermore, the System Codes are settable in 7 bits through the combination of KI0~KI6 and Code Key. Please
refer to the diagram below:
Key Nos.K8,16,24 and 32 (the Shift Keys ) can be pressed simultaneously or in any random order with other
keys (normal keys).
The system code setting is constructed by connecting the diode jumper between Code Key and KI0~KI6 keys.
With the diode jumper, the system code will have the value of “1”. If Code and any one of the KI0~KI6 keys are
connected only at one point, the diode jumper may be disregarded.
4.LED TERMINAL
When there is no key activity, the LED Pin is in the HIGH Level. Please refer to the diagram below.
