Error Response
• Error response, H'91, (1 byte)
• ERROR
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
• Command, H'22, (1 byte): Inquiry regarding multiplication ratio
Response
• Response, H'32, (1 byte): Response to the multiplication ratio inquiry
• Size (1 byte): The amount of data that represents the number of clock sources and
• Number of types (1 byte): The number of supported multiplied clock types
• Number of multiplication ratios (1 byte): The number of multiplication ratios for each type
• Multiplication ratio (1 byte)
• SUM (1 byte): Checksum
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.)
Division ratio: The inverse of the division ratio, i.e. a negative number (e.g. when the clock is
divided by two, the value of division ratio will be H'FE. H'FE = D'-2)
The number of multiplication ratios returned is the same as the number of multiplication ratios
and as many groups of data are returned as there are types.
