2.3 WRAL
This instruction writes the same 16-bit data into every address.
After changing CS to high, input a start-bit, op-code (WRAL), address (optional), 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 WRAL operation.
It is not necessary to make the data "1" before initiating the WRAL operation.
