(2) Flash memory mode 2 (serial I/O mode)
The flash memory version of the 3803/3804 group has a function
to serially input/output the software commands, addresses, and
data required for operation on the internal flash memory (e. g.,
read, program, and erase) using only a few pins. This is called the
serial I/O (input/output) mode. This mode can be selected by driv-
ing the SDA (serial data input/output), SCLK (serial clock input ),

In the serial I/O mode, the user can use six types of software com-
mands: read, program, program verify, erase, erase verify and
error check.
Serial input/output is accomplished synchronously with the clock,
beginning from the LSB (LSB first).
