7. 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.
