Custom Code Extension
The custom code high-order 8 bit Cn ( n = 0~7 ) are determined by diode attached to the CCS pin and KI/O
pins. If KI/Oi are connected to CCS by diode, Cn ( n = 0~7 ) =1. If KI/Oi are not connected to CCS by diode,
Cn ( n = 0~ 7 ) = 0.The custom code low-order 8 bit Cn’ ( n = 0 ~7)
are determined by pull-up resistor to the KI/O pins. If pull-up resistors are attached to the KI/Oi pins, Cn’= Cn.
If pull-up resistors are not attached to the KI/O PINS, Cn’= CnB.
