7.17 Command decoder
An acknowledgement after each byte is asserted only by the PCF8562s that are
addressed via address lines A0, A1 and A2. After the last display byte, the I
asserts a STOP condition (P). Alternately a START may be asserted to restart an I
access.
The command decoder identifies command bytes that arrive on the I
The commands available to the PCF8562 are defined in
Table 7.

All available commands carry a continuation bit C in their most significant bit position as
shown in
arrive will also represent a command. If this bit is reset, it indicates that the command byte
is the last in the transfer. Further bytes will be regarded as display data (see
