Flash Row Programming
The Flash memory can be programmed either as a single byte at a time or as a row of bytes
at a time. Multi-byte row programming allows programming of a full row of Flash
memory without incurring all of the programming setup and recovery time for each byte.
During row programming, the Flash memory’s PROG and NVSTR signals are
