Product data sheet
After an acknowledgement, one or more command bytes follow, that define the status of
each addressed PCF8576D.
The last command byte sent is identified by resetting its most significant bit, continuation
bit C, (see
PCF8576D on the bus.
After the last command byte, one or more display data bytes may follow. Display data
bytes are stored in the display RAM at the address specified by the data pointer and the
subaddress counter. Both data pointer and subaddress counter are automatically updated
and the data directed to the intended PCF8576D device.
An acknowledgement after each byte is asserted only by the PCF8576Ds that are
addressed via address lines A0, A1, and A2. After the last display byte, the I
master asserts a STOP condition (P). Alternately a START may be asserted to restart an
