During Write Cycle
WRITE COMMAND TABLE
Commands are written into the command register in one or two write cycles. The command register can be altered
only when V PP is high and the instruction byte is latched on the rising edge of WE. Write cycles also internally latch
addresses and data required for programming and erase operations.
