(f)
The boot program will return the number of operating clock frequencies, and the maximum and
minimum values.
Command
• Command, H'23, (one byte): Inquiry regarding operating clock frequencies
Response
• Response, H'33, (one byte): Response to operating clock frequency inquiry
• Size (one byte): The number of bytes that represents the minimum values, maximum values,
• Number of operating clock frequencies (one byte): The number of supported operating clock
• Minimum value of operating clock frequency (two bytes): The minimum value of the
• Maximum value (two bytes): Maximum value among the multiplied or divided clock
• SUM (one byte): Checksum
and the number of frequencies.
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.)
multiplied or divided clock frequency.
The minimum and maximum values of the operating clock frequency represent the values in
MHz, valid to the hundredths place of MHz, and multiplied by 100. (e.g. when the value is
17.00 MHz, it will be 2000, which is H'07D0.)
frequencies.
There are as many pairs of minimum and maximum values as there are operating clock
frequencies.
