PCA85233

Automotive 80 × 4 LCD driver for low multiplex rates

The command bytes and control bytes are also acknowledged by all addressed

PCA85233 connected to the bus.

The display 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.

The acknowledgement after each byte is made only by the (A0 and A1) addressed

PCA85233. After the last display byte, the I2C-bus master issues a STOP condition (P).

Alternatively a START may be asserted to RESTART an I2C-bus access.
