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.
