MB90470 Series

8/16-bit PPG

The 8/16-bit PPG is an 8-bit reload timer module that produces a PPG output in the form of a pulse for timer

operation. The hardware configuration includes six 8-bit down counters, twelve 8-bit reload timers, three 16-bit

control registers, six external pulse output pins, and six interrupt outputs. The MB90470 provides six 8-bit PPG

channels, which can also operate as three 16-bit PPG channels in the combination PPG0

+ PPG1, PPG2 +

PPG3, PPG4

+ PPG5. The following is an overview of the functions of the PPG.

• Six-channel independent 8-bit PPG output mode : Provides PPG output operation independently on six

channels.

• 16-bit PPG output operation mode : Provides 16-bit PPG output operation on three channels, using the

combination PPG0

+ PPG1, PPG2 + PPG3, PPG4 + PPG5.

•8

+ 8-bit PPG output operation mode :

Uses the PPG0 (PPG2/PPG4) output as the PPG1 (PPG3/PPG5) clock input, to enable 8-bit PPG output with

any desired period.

• PPG output operation :

Outputs pulse waves at a specified period and duty ratio.

Can be also used with an external circuit as a D/A converter.
