(2) Flash memory mode 2 (serial I/O mode)
The M38869FFAHP/GP 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) us-
ing only a few pins. This is called the serial I/O (input/output)
mode. This mode can be selected by driving the SDA (serial data
input/output), SCLK (serial clock input ), and OE pins high after
connecting wires as shown in Figures 72 and powering on the V
CC
pin and then applying V
PP
H to the V
PP
pin.
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).
