(b) Device Selection
The boot program will set the supported device to the specified device code in response to the
device selection. The program will return the selected device code in response to the inquiry after
this setting has been made.
• Command, H'10, (1 byte): Device selection
• Size (1 byte): Amount of device-code data
• Device code (4 bytes): Device code (ASCII code) returned in response to the supported device
• SUM (1 byte): Checksum
• Response, H'06, (1 byte): Response to the device selection command
• Error response, H'90, (1 byte): Error response to the device selection command
(c)
The boot program will return the supported clock modes in response to the clock mode inquiry.
• Command, H'21, (1 byte): Inquiry regarding clock mode
• Response, H'31, (1 byte): Response to the clock-mode inquiry
• Size (1 byte): Amount of data that represents modes
• Mode (1 byte): Values of the supported clock modes (i.e. H'01 means clock mode 1.)
• SUM (1 byte): Checksum
