Dear support team;
I use 913A-EVM and 914A-EVM.
After the following sequence , I2C communication locked.
- Operation mode is PCLK mode.
- There is no clock at PCLK pin.
1st step : BISTEN = 0
I can have access to DS90UB913A via I2C.
2nd step : BISTEN = 1
I cannot have access to DS90UB913A via I2C.
LOCK pin is 0.
3rd step : BISTEN = 0
I cannot have access to DS90UB913A via I2C.
I tried BIST mode via pin and register, but there are same status.
Is this state correct ?
Best Regards,
M.Sugiyama
