• Number of multipliers (1 byte): The number of selectable frequency multipliers and divisors

for the device.

This is normally 2, which indicates the main operating frequency and the operating frequency

of the peripheral modules.

• Multiplier 1 (1 byte): Multiplier or divisor for the main operating frequency

Multiplier: Numerical value of the frequency multiplier (e.g. H'04 for

×4)

Divisor: Two’s complement negative numerical value in the case of frequency division (e.g.

H'FE [-2] for

×1/2)

• Multiplier 2 (1 byte): Multiplier or divisor for the peripheral operating frequency

Multiplier: Numerical value of the frequency multiplier (e.g. H'04 for

×4)

Divisor: Two’s complement negative numerical value in the case of frequency division (e.g.

H'FE [-2] for

×1/2)

• SUM (1 byte): Checksum

Response

H'06

• Response H'06 (1 byte): Response to the new-bit-rate selection command

This is the ACK code and is returned if the specified bit rate is selected.

Error

response

H'BF

ERROR

• Error response H'BF (1 byte): Error response to the new-bit-rate selection command

• ERROR (1 byte): Error code

H'11: Sum-check error

H'24: Bit rate selection error (the specified bit rate is not selectable).

H'25: Input frequency error (the specified input frequency is not within the range from the

minimum to the maximum value).

H'26: Frequency multiplier error (the specified multiplier does not match an available one).

H'27: Operating frequency error (the specified operating frequency is not within the range

from the minimum to the maximum value).
