... SI High-Impedance SO © 2009 Microchip Technology Inc. Once the write enable latch is set, the user may proceed by setting the CS low, issuing a WRITE instruc- tion, followed by the 16-bit address, and then the data to be written. Depending upon the density, a page of data that ranges from 16 bytes to 64 bytes can be sent to the device before a write cycle is necessary ...
