Electronic control apparatus and method for writing backup data in electronic control apparatus
摘要：
When a power switch is turned OFF, the execution of steady process is stopped, and backup data is written into a flash memory. If the power switch is turned ON during the writing of the backup data, the backup data writing execution is allowed to last for a predetermined time T1 after an instant when the power switch is turned ON, and if the writing of the backup data is not terminated at the time when the predetermined time T1 has elapsed, the writing of the backup data is interrupted so that the steady process is started for being executed.
摘要（中）：

当电源开关关闭时，停止执行稳定过程，并将备份数据写入闪存。 在备份数据的写入期间，如果电源开关被接通，则备用数据写入执行在电源开关接通之后允许持续预定时间T 1，并且备份数据的写入是 在经过预定时间T 1的时刻没有终止，备份数据的写入被中断，从而开始执行稳定处理。
