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.

7.1.1

HARDWIRED 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 VDD1 or VSS1.
