Appendix Standard Serial I/O Mode (Flash Memory Version)
238
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 serial. There are actually two
standard serial I/O modes: mode 1, which is clock synchronized, and mode 2, which is asynchronized. Both
modes require 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's rewrite mode), rewrite data input and so forth. It is started when the reset is re-
leased, which is done when the P5
level. (In the ordinary command mode, set CNVss pin to "L" level.)
This control program is written in the boot ROM area when the product is shipped from Mitsubishi. Accord-
ingly, make note of the fact that the standard serial I/O mode cannot be used if the boot ROM area is
rewritten in the parallel I/O mode. Figures 1.29.1 and 1.29.2 show the pin connections for the standard
serial I/O mode. Serial data I/O uses UART1 and transfers the data serially in 8-bit units. Standard serial I/
O switches between mode 1 (clock synchronized) and mode 2 (clock asynchronized) according to the level
of CLK
To use standard serial I/O mode 1 (clock synchronized), set the CLK
The operation uses the four UART1 pins CLK

To use standard serial I/O mode 2 (clock asynchronized), set the CLK
reset. The operation uses the two UART1 pins RxD
In the standard serial I/O mode, only the user ROM area indicated in Figure 1.29.19 can be rewritten. The
boot ROM cannot.
In the standard serial I/O mode, a 7-byte ID code is used. When there is data in the flash memory, com-
mands sent from the peripheral unit are not accepted unless the ID code matches.
