Flashrite Programming Algorithm

Notes:

1. See AC and DC Characteristics for values of VPP parameters. The VPP power supply can be hard-wired to the device or

switchable. When VPP is switched, VPPL may be ground, no connect with a resistor tied to ground, or less than VCC + 2.0 V.

Program Verify is performed only after byte programming. A final read/compare may be performed (optional) after the register

is written with the read command.
