(d) Clock Mode Selection
The boot program will set the specified clock mode in response to the clock mode selection. The
program will return the selected clock-mode information after this setting has been made.
The clock-mode selection command should be sent after the device-selection commands.
• Command, H'11, (1 byte): Selection of clock mode
• Size (1 byte): Amount of data that represents the modes
• Mode (1 byte): A clock mode returned in reply to the supported clock mode inquiry.
• SUM (1 byte): Checksum
• Response, H'06, (1 byte): Response to the clock mode selection command
• Error response, H'91, (1 byte): Error response to the clock mode selection command
• ERROR, (1 byte): Error code
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.
