updata status一直是04

Other Parts Discussed in Thread: BQ40Z50

您好,有三个问题请教下。

1、请问下为什么我ID学习,updata status总是到不了05。已经按照这个步骤操作了:

A typical C/2 charge rate is recommended; however, the charge rate is of no consequence.
Make sure IT is already enabled at this point before the start of charge (the [Gauge_EN] bit in the
manufacturing status() register should be set).
At the start of charge, the [VOK] bit in the IT status () register sets automatically.
At the end of charge the [FC] bit in the Battery Status () register should be set automatically. If it did
not set then a full charge was not properly detected and the learning cycle fails. Correct either the
charging conditions or the relevant dataflash settings to ensure the [FC] bit gets set and try again from
the beginning
2、放电之前发0x41 VOK置1,RDIS置0,再发0X21则VOK置0,RDIS置1.请问放电过程VOK和RDIS应该处于什么状态。我看TI文档,看到了两个说法。
3、MAXerror一直是100%这个没影响吧,学习成功会自动变为1%吧?
