DESCRIPTION
6 INSTRUCTIONS
The PCF8833 communicates with the host using an 8-bit parallel interface or a 3-line serial interface. Processing of
instructions and data sent to the interface do not require the display clock. The display clock and interface clock are
independent from each other. The display clock is derived from the built-in oscillator.
The PCF8833 has 2 types of accesses; those defining the operating mode of the device (instructions) and those filling
the display RAM. Since writing to the RAM occurs more frequently, efficient data transfer is achieved by
autoincrementing the RAM address pointers.
There are 3 types of instructions:
1. For defining display configuration
2. For setting X and Y addresses
3. Miscellaneous.
Commands in the range of 00H to AFH not defined in Table 1 and command DDH have the same effect as no operation
(NOP).
All commands in range B0H to B9H and DEH to FFH are forbidden.
