Hi,

I'm using host processor communicates via i2c to configure CY8CMBR3116 device. After sending 128bytes of configuration, I send command 0x02 to CTRL_CMD register. Documentation says that write operation takes 220ms, and after this time there should be 0x00 in CTRL_CMD register. I get 0x00 but after about 600ms. After this, device works correctly. Is this correct behavior? Mayby I should not check CTRL_CMD register for 0x00, only wait 250 ms and check CTRL_CMD_STATUS?

Thanks for your feedback. You confirm what I supposed. I hope we are both right.
