(6) Operating Clock Frequency Inquiry
The boot program will return the number of operating clock frequencies, and the maximum and
minimum values.
Command H'23
Response
Rev. 2.0, 06/04, page 654 of 980
A number of multiplication ratios (1 byte) : The number of multiplication ratios for 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 (1 byte)
Command, H'23, (1 byte) : Inquiry regarding operating clock frequencies
Response, H'33, (1 byte) : Response to operating clock frequency inquiry
Size (1 byte) : The number of bytes that represents the minimum values, maximum values,
and the number of types.
A number of types (1 byte) : The number of supported operating clock frequency types
(e.g. when there are two operating clock frequency types, which are the main and
peripheral clocks, the number of types will be H'02.)
Minimum value of operating clock frequency (2 bytes) : The minimum value of the
multiplied or divided clock frequency.
The minimum and maximum values represent the values in MHz, valid to the hundredths
place of MHz, and multiplied by 100. (e.g. when the value is 20.00 MHz, it will be D'2000
and H'07D0.)
Maximum value (2 bytes) : Maximum value among the multiplied or divided clock
frequencies.
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.
