8/16-bit PPG
The 8/16-bit PPG is an 8-bit reload timer module that produces a PPG output using a pulse from the timer
operation. Hardware resources include 6
× 8-bit down counters, 12 × 8-bit reload timers, 3 × 16-bit control
registers, 6
× external pulse output pins, and 6 × interrupt outputs. Note that MB90480B/485B series has six
channels for 8-bit PPG use, which can also be combined as PPG0
+ PPG1, PPG2 + PPG3, and PPG4 + PPG5
to operate as a three-channel 16-bit PPG. The following is a summary of functions.
8-bit PPG output 6-channel independent mode : Provides PPG output operation on six independent channels.
16-bit PPG output operation mode : Provides 16-bit PPG output on three channels. The six original channels
are used in combination as PPG0
+ PPG1, PPG2 + PPG3, and PPG4 + PPG5.
8
+ 8-bit PPG output operation mode : Output from PPG0 (PPG2/PPG4) is used as clock input to PPG1 (PPG3/
PPG5) to provide to 8-bit PPG output at any desired period length.
PPG output operation : Produces pulse waves at any desired period and duty ratio. The PPG module can also
be used with external circuits as a D/A converter.
