Hello,

We wrote data 0x81 at general registers address 0x0 and after that,

read general registers data was 0x3c .

but In datasheet,I can see bit [6:1] is all "0".

so I am littlebit confused. Is this right action？

User,

Bits 6:1 are not readable and default to a "011110" if you read these back. Bits 7 and 0 are self clearing and will always readback as "0". What you are reading is correct.

Regards,

Jim
