RTC-scratch registers reset value

$
0
0

Hi All

I am a bit confused about the RTC module's scratch registers which are general purpose registers.

i was trying to read form those registers after a power up sequence and i was expecting to see the reset value mentioned in the data sheet which is 0, but instead i get  a different values

the values i get are:

in scratch register 0 0x00000000.

in  scratch register 1 0x00000100.

in scratch register  2 0x00200400.

isn't the expected value after hardware reset is 0x00000000 ?

even if i unplug the device from any voltage supply and give it a few minute reset i see  those unexpected values.

1.has any one encountered such behavior running rtc module ?

2. do i need to call software reset prior to reading those registers?
