I encounter one problem with setting LTC6813 config registers.
I try to write config to LTC6813 IC and read it back, but the read back result is not match with what I written or default value.
Shown as following figure,
step 1 - I try to read back config setting after LTC6813 power up
step 2 - write config
step 3- read back config
My devices connection are PC <=USB=> DC2026C <=14-Pin Cable=> DC1941D <=IsoSPI=> DC2350A-B(IsoSPI-A)
Is there any problem with my connection or operation?
Please refer to Table 56. Memory Bit Description, in datasheet. Some of the bits have different write and read definitions.
Thanks for your information.
After some testing, I have one assumption
1. Config register would reset to default value when entering sleep mode
Is this correct?
In my experience with other IC, config register would not reset when entering sleep mode.
Yes, The IC resets Config registers when entering the sleep mode.
