• Inquiry-and-Selection State
In this state, the boot program returns information on the flash ROM in response to inquiry
commands sent from the host, and selects the device, clock mode, and bit rate in response to the
respective selection commands.
The inquiry and selection commands are listed in table 23.13.
Table 23.13 Inquiry and Selection Commands
The selection commands should be sent by the host in this order: device selection (H'10), clock-
mode selection (H'11), new bit rate selection (H'3F). These commands are mandatory. If the same
selection command is sent two or more times, the command that is sent last is effective.

respective values.
Selects a clock mode.
Requests the number of clock signals for which frequency
multipliers and divisors are selectable, the number of
multiplier and divisor settings for the respective clocks, and
the values of the multipliers and divisors.
Requests the minimum and maximum values for operating
frequency of the main clock and peripheral clock.
Requests the number of user boot MAT areas along with
their start and end addresses.
Requests the number of user MAT areas along with their
start and end addresses.
Requests the number of erasure blocks along with their
start and end addresses.
Requests the unit of data for programming.
Selects a new bit rate.
On receiving this command, the boot program erases the
user MAT and user boot MAT and enters the
programming/erasure state.
Requests information on the current state of boot
processing.
