var byte _x9c10x_wiper_shadow
LOCAL VARIABLES -------------------------------- Shadow value of the current wiper position. Needed because the value cannot be read back and can only be changed by increment and decrement.
x9c10x_store()
Store the current wiper value in the non volatile memory of the chip.
x9c10x_increment()
Increment the location of the wiper to change pot resistance but do not store it in the non volatile memory of the chip.
x9c10x_decrement()
Decrement the location of the wiper to change pot resistance but do not store it in the non volatile memory of the chip.
x9c10x_init()
Inititialize wiper and put it at X9C10X_MIN_VALUE.
x9c10x_wiper'put(byte in value)
Set the location of the wiper to change pot resistance but do not store it in the non volatile memory of the chip. Value must be in range X9C10X_MIN_VALUE .. X9C10X_MAX_VALUE.
