CHAPTER 12 8/16-BIT PPG
12.1 Overview of the 8/16-Bit PPG
The 8/16-bit PPG is an 8/16-bit reload timer module. Based on timer operation, the
module performs pulse output control to allow PPG output. The MB90550A/B Series
contains three 8/16-bit PPGs.
■ Overview of the 8/16-bit PPG
The 8/16-bit PPG consists of two 8-bit down counters, four 8-bit reload registers, three 8-bit
control registers, two external pulse output pins, and two interrupt outputs. Outputs a pulse
waveform with an arbitrary cycle period and duty cycle. The PPG can also be used as a D/A
converter when a circuit is connected externally. The PPG provides the following functions:
❍ 8-bit PPG output in 6-channel independent operation mode (8-bit PPG 2-ch mode)
Allows 6-channel independent PPG output operation.
❍ 16-bit PPG output operation mode (16-bit PPG 1-ch mode)
Allows 3-channel 16-bit PPG output operation.
❍ Pair 8- bit-prescaler + 8-bit - PPG mode
Allows 8-bit PPG output operation with an arbitrary cycle period by applying ch.0/ch.2/ch.4
output to the ch.1/ch.3/ch.5 clock input.
