Section 20 Flash Memory (0.18-μm F-ZTAT Version)
(k) New Bit-Rate Selection
The boot program will set a new bit rate and return the new bit rate.
This selection should be sent after sending the clock mode selection command.
Command
• Command, H'3F, (one byte): Selection of new bit rate
• Size (one byte): The number of bytes that represents the bit rate, input frequency, number of
• Bit rate (two bytes): New bit rate
• Input frequency (two bytes): Frequency of the clock input to the boot program
• Number of multiplication ratios (one byte): The number of multiplication ratios to which the
• Multiplication ratio 1 (one byte) : The value of multiplication or division ratios for the main
• Multiplication ratio 2 (one byte): The value of multiplication or division ratios for the
• SUM (one byte): Checksum
Response
• Response, H'06, (one byte): Response to selection of a new bit rate

multiplication ratios, and multiplication ratio
One hundredth of the value (e.g. when the value is 19,200 bps, the bit rate is H'00C0, which is
D'192.)
This is valid to the hundredths place and represents the value in MHz multiplied by 100. (e.g.
when the value is 64 MHz, the input frequency is H'1900 (= D'6400).)
device can be set.
operating frequency
Multiplication ratio (one byte): The value of the multiplication ratio (e.g. when the clock
frequency is multiplied by four, the multiplication ratio will be H'04.)
Division ratio: The inverse of the division ratio, as a negative number (e.g. when the clock
frequency is divided by two, the value of division ratio will be H'FE. H'FE = D'-2)
peripheral frequency
Multiplication ratio (one byte): The value of the multiplication ratio (e.g. when the clock
frequency is multiplied by four, the multiplication ratio will be H'04.)
(Division ratio: The inverse of the division ratio, as a negative number (E.g. when the clock is
divided by two, the value of division ratio will be H'FE. H'FE = D'-2)
When it is possible to set the bit rate, the response will be ACK.
