SPRS880O手册,1549页,章节10.2.2.5 本章节为ANAREFTRIMA寄存器,其中它的<10-6>位是字段BGSLOPETRIM功能,为带隙斜率调整。
其中00——不调整,其他值——调整
请问,是怎样去调整的?例如值为“01”,调整之后是多少?是正值还是负值?
字段<5-0>BGVALTRIM同以上疑问。谢谢解答。

你好,你是指的哪个文件?我搜索你发的文件名搜出来这个datasheet,但是它没有1549页。
你好,这些是不支持修改的。下面是工程师的回复:
These values are loaded during boot up with values we store in TI OTP memory by the BROM. These are used to meet the DS electrical requirements for the analog subsystem on the device across the operational range of the device.
There is no support for customer to "re-trim" or populate other values in these registers, so therefore we do not provide details on any functional usage of these registers. These are documented in the TRM so that it is known what these locations are used for by TI.
