User Application Note
(Before using this chip, take a look at the following description note, it includes important messages.)
1. There are some undefined bits in the registers. The values in these bits are unpredicted. These
bits are not allowed to use. We use the symbol “-” in the spec to recognize them. A fixed value
must be write in some specific unused bits by software or some unpredicted wrong will occur.
These bits are as below.
