Meaning of Co bit in US2066 Controller
« on: November 01, 2016, 04:50:29 PM »
I am using the I2C interface for the OLED display NHD-0420CW which uses a US2066 controller. The manual describes the Co bit in write mode but it is unclear what it really means. Since the D/C# bit defines whether the following byte will be interpreted as a Command or Data, I don't see that the Co bit has any useful function. Can someone tell me what it means?

Responded via. Email.

The Co bit is a continuation bit, that tells the controller that the byte coming in next is data and it should be read.
