Standard serial I/O Mode
The standard serial I/O mode inputs and outputs the software
commands, addresses and data needed to operate (read, program,
erase, etc.) the internal flash memory. This I/O is clock
synchronized serial. This mode requires a purpose-specific
peripheral unit.
The standard serial I/O mode is different from the parallel I/O
mode in that the CPU controls flash memory rewrite (uses the
CPU rewrite mode), rewrite data input and so forth. The standard
serial I/O mode is started by connecting “H” to the CNV
and “H” to the P4
operation. (In the ordinary microcomputer mode, set CNV
to “L” level.) This control program is written in the Boot ROM
area when the product is shipped from Renesas. Accordingly,
make note of the fact that the standard serial I/O mode cannot be
used if the Boot ROM area is rewritten in parallel I/O mode. The
standard serial I/ O mode has standard serial I/O mode 1 of the
clock synchronous serial and standard serial I/O mode 2 of the
clock asynchronous serial. Table 15 and 16 show description of
pin function (standard serial I/O mode). Figure.74 to 77 show the
pin connections for the standard serial I/O mode.
In standard serial I/O mode, only the User ROM area shown in
Figure.64 can be rewritten. The Boot ROM area cannot be
written.
In standard serial I/O mode, a 7-byte ID code is used. When there
is data in the flash memory, this function determines whether the
ID code sent from the peripheral unit (programmer) and those
written in the flash memory match. The commands sent from the
peripheral unit (programmer) are not accepted unless the ID code
matches.
