PPG (Programable Pulse Generator)
The PPG can efficiently output highly precise PWM waveforms.
The MB91F355A/MB91355A/MB91354A/MB91V350A contain six channels of PPG timer.
(1)Description
Each channel consists of a 16-bit down counter, 16-bit data register with cycle setting buffer, 16-bit compare
register with duty ratio setting buffer, and pin control unit.
The count clocks for the 16-bit down counter can be selected from the following four types :(peripheral clock
φ,
φ/4, φ/16, φ/64)
The counter is initialized to "FFFFH" at a reset or counter borrow.
PPG outputs (PPG0 to PPG5) are provided for each channel.
