To erase 16-bit data at a specified address, set all 16 bits of the data to 1, change CS to high, and then
input the ERASE instruction and address following the start bit. There is no need to input data. The data
erase operation starts when CS goes low. If the clocks more than the specified number have been input,
the clock pulse monitoring circuit cancels the ERASE instruction. For details of the clock pulse monitoring
circuit, refer to “ Function to Protect Against Write due to Erroneous Instruction Recognition ”.
