2.4 Functional Description
2.4.1 Flash Command Operations
Write and read operations are both used for the program, erase, erase verify, and data compress algorithms
described in this subsection. The program and erase algorithms are time controlled by a state machine
whose timebase, FCLK, is derived from the oscillator clock via a programmable divider. The command
