8/16-Bit PPG
The 8/16-bit PPG timer is a 2-channel reload timer module (PPG0, PPG1) capable of arbitrary synchronization
and pulse output of duty ratio. Combining the 2 channel module can yield the following behavior :
8-bit PPG output, 2-channel independent operation mode
16-bit PPG output operation mode
8
+
8-bit PPG output operation mode
The MB90495G Series features two on-chip, 8/16-bit PPG timers. This section describes the functions of PPG0/
1. PPG2/3 has the same functions as PPG0/1.
8/16-bit PPG Timer Functions
The 8/16-bit PPG timer is made up of four 8-bit reload registers (PRLH0/PRLL0, PRLH1/PRLL1) , and two PPG
down counters (PNT0, PCNT1) .
Since you can set each output pulse to “H” or “L” width independently, the interval and duty ratio of each
pulse can be set to an arbitrary value.
Select one of 6 internal clocks as the count clock.
Interrupt requests can be generated for each interval time, allowing the timer to be used as an interval timer.
The use of an external circuit allows the timer to be used as a D/A converter.
