Set Static Indicator State
Consists of two bytes instruction. The first byte instruction (set Static Indicator Mode) enables the second byte
instruction (set Static Indicator Register) to be valid. The first byte sets the static indicator ON /OFF. When it is on, the
second byte updates the contents of static indicator register without issuing any other instruction and this Static
Indicator state is released after setting the data of indicator register.

Test Instruction (Test Instruction_1 &Test Instruction_2)
Thee are the instruction for IC chip testing. Please do not use it. If the test instruction is used by accident,it can be
cleared by applying “0” signal to the RESET input pin or the reset instruction.
