Freescale Semiconductor, Inc.
Pulse Width Modulator (PWM8B8C)
software-selectable duty rates from 0% to 100%. The PWM outputs can
be programmed as left aligned outputs or center aligned outputs.
Features
• Eight independent PWM channels with programmable period and
duty cycle.
• Dedicated counter for each PWM channel.
• Programmable PWM enable/disable for each channel.
• Software selection of PWM duty pulse polarity for each channel.
• Period and duty cycle are double buffered. Change takes effect
when the end of the effective period is reached (PWM counter
reaches zero) or when the channel is disabled.
• Programmable center or left aligned outputs on individual
channels.
• Eight 8-bit channel or four 16-bit channel PWM resolution.
• Four clock sources (A, B, SA and SB) provide for a wide range of
frequencies.
• Programmable Clock Select Logic.
• Emergency shutdown.
Modes of Operation
