The boot program will return the supported multiplication and division ratios.
Command
• Command, H'22, (one byte): Inquiry regarding multiplication ratio
Response
• Response, H'32, (one byte): Response to the multiplication ratio inquiry
• Size (one byte): The amount of data that represents the number of types of multiplication, the
• Number of types of multiplication (one byte): The number of types of multiplication to which
• Number of multiplication ratios (one byte): The number of types of multiplication ratios for
• Multiplication ratio (one byte)
• SUM (one byte): Checksum
number of multiplication ratios, and the multiplication ratios
the device can be set
(e.g. when there are two multiplied clock types, which are the main and peripheral clocks, the
number of types will be H'02.)
each type
(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 = [-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 of multiplication.
