Command
Response
 Command H'23 (1 byte): Inquiry on operating frequency
 Response H'33 (1 byte): Response to the inquiry on operating frequency
 Size (1 byte): The total length of the number of operating clocks, and maximum and
 Number of operating clocks (1 byte): The number of operating clock frequencies required
 Minimum value of operating frequency (2 bytes): The minimum frequency of a frequency-
 Maximum value of operating frequency (2 bytes): The maximum frequency of a frequency-
 SUM (1 byte): Checksum
Inquiry on operating frequency
minimum values of operating frequency fields.
within the device.
For example, the value two indicates main and peripheral operating clock frequencies.
multiplied or -divided clock signal.
The value in this field and in the maximum value field is the frequency in MHz to two
decimal places, multiplied by 100 (for example, if the frequency is 20.00 MHz, the value
multiplied by 100 is 2000, so H'07D0 is returned here).
multiplied or -divided clock signal.
As many pairs of minimum/maximum values are included as there are operating clocks.
