Error Response
• Error response, H'BF, (one byte): Error response to selection of new bit rate
• ERROR: (one byte): Error code
(4)
The methods for checking of receive data are listed below.
1. Input frequency
2. Multiplication ratio
3. Operating frequency
4. Bit rate
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.
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.
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.
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.
Receive Data Check
Operating frequency = Input frequency × Multiplication ratio, or
Operating frequency = Input frequency ÷ Division ratio
