FUNCTIONAL DESCRIPTION
7.1
MPU interfaces
The PCF8833 can interface to a microcontroller with an 8-bit parallel or a serial interface to transmit both data and
commands to the PCF8833.

ARDWIRED INTERFACE SELECTION
The selection of a given interface is done by setting pins PS0, PS1 and PS2 as shown in Table 81. Inputs PS1 and PS2
must be connected to V
DD1
or V
