Minimum byte programming time excluding system overhead is 16 μsec (10 μsec program + 6 μsec write recovery), while
maximum is 400 μsec/byte (16 μsec x 25 loops allowed by algorithm). Max chip programming time is specified lower than
the worst case allowed by the programming algorithm since most bytes program significantly faster than the worst case
byte.
Excludes 00H programming prior to erasure.
Excludes system level overhead.
