Product data sheet
Having two reserved slave addresses allows the following on the same I
The I
condition (S) from the I
slave addresses available. All PCF85162 whose SA0 inputs correspond to bit 0 of the
slave address respond by asserting an acknowledge in parallel. This I
ignored by all PCF85162 whose SA0 inputs are set to the alternative level.
After an acknowledgement, one or more command bytes follow, that define the status of
each addressed PCF85162.
The last command byte sent is identified by resetting its most significant bit, continuation
bit C, (see
PCF85162s 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 PCF85162 device.
An acknowledgement after each byte is asserted only by the PCF85162 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
