 Programming unit (two bytes): Unit for programming
This is the unit for reception of program data.
 SUM (one byte): Checksum
(11) Inquiry of Two-MAT Simultaneous Programming
For an inquiry of two-MAT simultaneous programming, the boot program returns the response
whether two-MAT simultaneous programming is possible or not, and the start address.
Command H'28
 Command: H'28 (one byte): Inquiry of two-MAT simultaneous programming
Response H'38 Size Programming method
First MAT start address
Second MAT start address
SUM
 Response: H'38 (one byte): Response to the inquiry of two-MAT simultaneous
programming
 Size (one byte): Total amount of programming method and MAT start address
5 bytes when programming to one MAT, 9 bytes when programming to two MATs
simultaneously
 Programming method (one byte): H'01 = One-MAT programming
H'02 = Two-MAT simultaneous programming
 First MAT start address (four bytes): First MAT start address
 Second side MAT start address four bytes): Second MAT start address
 Data on second MAT start address is available only when two-MAT simultaneous
programming is possible.
 SUM (one byte): Checksum
(12) 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 H'3F
Size
Bit rate
Input frequency
Number of
Multiplication Multiplication
multiplication ratios ratio 1
ratio 2
SUM
 Command: H'3F (one byte): Selection of new bit rate
 Size (one byte): Amount of data that represents the bit rate, input frequency, number of
multiplication ratios, and multiplication ratios
 Bit rate (two bytes): New bit rate
One hundredth of the value (e.g. when the value is 19200 bps, the bit rate is 192, which is
H’00C0)
