Device Commands
When the VPEN voltage ≤ VPENLK, only read operations from the Status Register, CFI, identifier
codes, or blocks are enabled. Placing VPENH on VPEN additionally enables block erase, program,
and lock-bit configuration operations. Device operations are selected by writing specific
commands into the CUI. Table 14, “Command Bus-Cycle Definitions†on page 35 defines these
commands.
