Section 17 Flash Memory
 Response H'36 (1 byte): Response to the inquiry on erasure blocks
 Size (2 bytes): The total length of the number of blocks and first and last address fields.
 Number of blocks (1 byte): The number of erasure blocks in flash memory
 First address of the block (4 bytes)
 Last address of the block (4 bytes)
As many pairs of first and last address data are included as there are blocks.
 SUM (1 byte): Checksum
(9) Inquiry on programming size
In response to the inquiry on programming size, the boot program returns the size, in bytes, of the
unit for programming.
Command H'27

SUM
 Response H'37 (1 byte): Response to the inquiry on programming size
 Size (1 byte): The number of characters in the programming size field (fixed at 2)
 Programming size (2 bytes): The size of the unit for programming
This is the unit for the reception of data to be programmed.
 SUM (1 byte): Checksum
(10) New bit rate selection
In response to the new-bit-rate selection command, the boot program changes the bit rate setting to
the new bit rate and, if the setting was successful, responds to the ACK sent by the host by
returning another ACK at the new bit rate.
The new-bit-rate selection command should be sent after clock-mode selection.
