Section 8 8-Bit PWM Timer (PWM)
Section 8 8-Bit PWM Timer (PWM)
This LSI has an on-chip pulse width modulation (PWM) timer with eight outputs. Eight output
waveforms are generated from a common timebase, enabling PWM output with a high carrier
frequency to be produced using pulse division.
8.1
Features
• Operable at a maximum carrier frequency of 1.25 MHz using pulse division (at 20-MHz
operation)
• Duty cycles from 0 to 100% with 1/256 resolution (100% duty realized by port output)
• Direct or inverted PWM output, and PWM output enable/disable control
