    • A transmission method uses multiple kinds of control codes to be exchanged on a serial transmission path between a sender side and a receiver side, and each of the multiple kinds of control codes has bits smaller in number than a predetermined fixed length. The transmission method includes the steps of inspecting the received bit string in groups of bits of the number of the control code, and thereby determining whether one of the multiple kinds of control codes is present in the serial signal received on the serial transmission path or not, selecting the control code to be sent based on a result of the determination in the determining step, sending, onto the serial transmission path, a bit string containing at least the control code to be sent based on the result of the determination in the determining step, and receiving the data code by inspecting the received bit string in groups of bits of the fixed length in response to the detection of the control code indicating the start of transmission of the data from the opposite side in the determining step.

    • A bitstream analysis circuit, generates a reference clock control data. A reference clock DPLL receives a system clock signal and reference clock control data from the analysis circuit and generates a reference clock signal. The reference clock DPLL comprises a 1/n frequency dividing circuit for frequency-dividing the system clock signal, and a 1/(n+1) frequency dividing circuit for frequency-dividing the system clock signal. A register stores data to set frequency dividing ratios of both frequency dividing circuits. A mixing ratio set register stores data to set a mixing ratio between output clock signals from both frequency dividing circuits and a mixing circuit, and mixes the output clock signals from both frequency dividing circuits at a mixing ratio in response to the data in the mixing ratio setting register.

    • A control section sets a value “1” to a first flip-flop when a core executes a halt instruction. An OR circuit halts to output the clock. When the detection section detects an occurrence of the exception request, the control section copies the value “1” of the first flip-flop to a second flip-flop and then sets the value “0” to the first flip-flop to restart the supply of the clock to the core through the circuit. When detecting that the value “1” is set in the second flip-flop, the core judges that the state of the core was in the halt state when the exception request occurred, the core returns to the halt state after the completion of the exception handling by executing the halt instruction. When the second flip-flop does not store the value “1”, the core executes an instruction next to the address of the halt instruction.
    • 当核心执行停止指令时,控制部分向第一触发器设置值“1”。 OR电路停止输出时钟。 当检测部分检测到异常请求的发生时,控制部分将第一触发器的值“1”复制到第二触发器,然后将值“0”设置到第一触发器以重新开始 通过电路将时钟提供给核心。 当检测到第二个触发器中设置了值“1”时,核心在发生异常请求时判断核心的状态处于停止状态,核心在完成异常之后返回到停止状态 通过执行停止指令进行处理。 当第二触发器不存储值“1”时,核心执行停止指令的地址旁边的指令。
