(9)
In response to the inquiry on programming size, the boot program returns the size, in bytes, of the
unit for programming.
(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.
