Section 20 Flash Memory
• Response, H'06, (one byte): Response to the clock mode selection command
• Error response, H'91, (one byte) : Error response to the clock mode selection command
• ERROR, (one byte): Error code
Even if the clock mode numbers are H'00 and H'01 by a clock mode inquiry, the clock mode must
be selected using these respective values.
(e) Multiplication Ratio Inquiry
The boot program will return the supported multiplication and division ratios.
• Command, H'22, (one byte): Inquiry regarding multiplication ratio
• Response, H'32, (one byte): Response to the multiplication ratio inquiry
• Size (one byte): The amount of data that represents the number of clock sources and
• Number of types (one byte): The number of supported multiplied clock types
• Number of multiplication ratios (one byte): The number of multiplication ratios for each type
• Multiplication ratio (one byte)

Error Response
Command
Response
ACK will be returned when the clock mode matches.
multiplication ratios and the multiplication ratios
(e.g. when there are two multiplied clock types, which are the main and peripheral clocks, the
number of types will be H'02.)
(e.g. the number of multiplication ratios to which the main clock can be set and the peripheral
clock can be set.)
Multiplication ratio: The value of the multiplication ratio (e.g. when the clock-frequency
multiplier is four, the value of multiplication ratio will be H'04.)
H'11: Checksum error
H'22: Clock mode error, that is, the clock mode does not match.
