HI, Iam working on the RTC driver(Windows Embedded Compact 7 on AM335x based custom platfrom) using the TPS65910. I need to enable the battery backup using the BBCH_REG. I am writing 0x03 into the register that is (BBSEL=2.52V and BBCHEN=1), But some how when i read this after after the setting , it shows the value as 0x04. Is there any sequency or pre-condition to write into this register.
Regards
