Selection and Setting of Functions

SM5879AV offers a variety of functions. Fundamen-

tally, there are two methods available for selecting

and setting these functions.

One method is using an external input pin; this is

called parallel setting. The other method is by using

the microcontroller interface, which is called micro-

controller setting.

Microcontroller interface refers here to serial data

transfer from the microcontroller using the three pins

MDT, MCK, and MLEN.

These two methods of setting and selection are set by

the P/M pin.

When P/M is HIGH, parallel setting is used.

When P/M is LOW, microcontroller setting is used.
