Some parametric limits are subject to
(3) Standard serial I/O Mode
The standard serial I/O mode inputs and outputs the software
commands, addresses and data needed to operate (read, pro-
gram, erase, etc.) the internal flash memory. This I/O is clock
synchronized serial. This mode requires a purpose-specific pe-
ripheral unit.
