2.1 WRITE

This instruction writes 16-bit data to a specified address.

After changing CS to high, input a start-bit, op-code (WRITE), address, and 16-bit data. If there is a data overflow of more

than 16 bits, only the last 16 bits of the data is considered valid. Changing CS to low will start the WRITE operation. It is not

necessary to make the data "1" before initiating the WRITE operation.
