(11) 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
multiplication ratios, and multiplication ratio
One hundredth of the value (e.g. when the value is 19200 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 20.00 MHz, the input frequency is H'07D0 (= D'2000).)
device can be set. Normally the value is two: main operating frequency and peripheral module
operating frequency.
operating frequency
⎯ Multiplication ratio (1 byte): The value of the multiplication ratio (e.g. when the clock
⎯ Division ratio: The inverse of the division ratio, as a negative number (e.g. when the clock
frequency
⎯ Multiplication ratio (1 byte): The value of the multiplication ratio (e.g. when the clock
⎯ Division ratio: The inverse of the division ratio, as a negative number (e.g. when the clock
frequency is multiplied by four, the multiplication ratio will be H'04. With this LSI it
should be set to H'01.)
frequency is divided by two, the value of division ratio will be H'FE. H'FE = D'-2. With
this LSI it should be set to H'01.)
