16-bit PPG Timer (
× 3, PPG1 is not present in MB90465 series)
The 16-bit PPG timer consists of a 16-bit down counter, prescaler, 16-bit period setting buffer register, 16-bit
duty setting buffer register, 16-bit control register and a PPG output pin. This module can be used to output
pulses synchronized by software trigger or GATE signal from Multi-functional timer, refer to “Multi-functional
Timer”
Features of 16-bit PPG Timer :
Two operating mode : PWM and One-shot
8 types of counter operation clock (
φ, φ/2, φ/4, φ/8, φ/16, φ/32, φ/64, φ/128) can be selected
Interrupt generated when trigger signal arrived, or counter borrow, or change of PPG output
EI2OS supported
