HD6412373R RENESAS [Renesas Technology Corp], HD6412373R Datasheet - Page 1005

• Manufacturer Part Number: HD6412373R
• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family/H8S/2300 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

Error Response
• Error response, H'BF, (one byte): Error response to selection of new bit rate
• ERROR: (one byte): Error code
(5)
The methods for checking of received data are listed below.
1. Input frequency
The received value of the input frequency is checked to ensure that it is within the range of
minimum to maximum frequencies which matches the clock modes of the specified device. When
the value is out of this range, an input-frequency error is generated.
2. Multiplication ratio
The received value of the multiplication ratio or division ratio is checked to ensure that it matches
the clock modes of the specified device. When the value is out of this range, an input-frequency
error is generated.
3. Operating frequency error
Operating frequency is calculated from the received value of the input frequency and the
multiplication or division ratio. The input frequency is input to the LSI and the LSI is operated at
the operating frequency. The expression is given below.
Operating frequency = Input frequency × Multiplication ratio, or
Operating frequency = Input frequency ÷ Division ratio
The calculated operating frequency should be checked to ensure that it is within the range of
minimum to maximum frequencies which are available with the clock modes of the specified
device. When it is out of this range, an operating frequency error is generated.
