PCF85176
Universal LCD driver for low multiplex rates
After an acknowledgement, one or more command bytes follow that define the status of
each addressed PCF85176.
The last command byte sent is identified by resetting its most significant bit, continuation
bit C (see
Figure 19
). The command bytes are also acknowledged by all addressed
PCF85176 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 PCF85176 device.
An acknowledgement after each byte is asserted only by the PCF85176 that are
addressed via address lines A0, A1, and A2. After the last display byte, the I
2
C-bus
master asserts a STOP condition (P). Alternately a START may be asserted to restart an
I
2
C-bus access.
