    • A serial communication system includes a master processor and a slave processor. A CS signal for requesting a serial communication is output from the master processor, and an OK_INV signal for responding to the CS signal is output from the slave processor. When a CS signal is an active state, the master processor executes a serial communications of a preset number of bits every time that a level of the OK_INV signal is reversed. The slave processor inverts a level of an OK_INV signal in response to the CS signal shifting to the active state. The slave processor changes the level of the OK_INV signal every time that a serial communication of a preset number of bits is completed.
    • 串行通信系统包括主处理器和从属处理器。 从主处理器输出用于请求串行通信的CS信号,并且从从属处理器输出用于响应CS信号的OK_INV信号。 当CS信号是活动状态时,主处理器每当OK_INV信号的电平反转时执行预置位数的串行通信。 响应于CS信号转换到活动状态,从属处理器反转OK_INV信号的电平。 每当完成预置位数的串行通信时,从器件处理器改变OK_INV信号的电平。
