(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, (1 byte): Selection of new bit rate
• Size (1 byte): The number of bytes that represents the bit rate, input frequency, number of
• Bit rate (2 bytes): New bit rate
• Input frequency (2 bytes): Frequency of the clock input to the boot program
• Number of multiplication ratios (1 byte): The number of multiplication ratios to which the
• Multiplication ratio 1 (1 byte) : The value of multiplication or division ratios for the main
• Multiplication ratio 2 (1 byte): The value of multiplication or division ratios for the peripheral
• SUM (1 byte): Checksum
Response
• Response, H'06, (1 byte): Response to selection of a new bit rate
Error Response
• Error response, H'BF, (1 byte): Error response to selection of new bit rate
multiplication ratios, and multiplication ratio
One hundredth of the value (e.g. when the value is 19200 bps, it will be 192, which is
H′00C0.)
This is valid to the hundredths place and represents the value in MHz multiplied by 100. (E.g.
when the value is 20.00 MHz, it will be 2000, which is H'07D0.)
device can be set.
operating frequency
Multiplication ratio (1 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)
frequency
Multiplication ratio (1 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.
