The major changes are :
complement the PSCOUT01, PSCOUT11, PSCOUT21 polarity in
centered mode - See “PSCn0 & PSCn1 Basic Waveforms in
Center Aligned Mode” on page 138.
Add the PSC software triggering capture - See “PSC 0 Input
Capture Register – PICR0H and PICR0L” on page 169.
Add bits to read the PSC output activity - See “PSC0 Interrupt
Flag Register – PIFR0” on page 171.
Add some clock configurations - See “Device Clocking Options
Select (1) AT90PWM2B/3B” on page 31.
Change Amplifier Synchonization - See “Amplifier” on page 250.
and See “Amplifier synchronization timing diagram for
PWM2B/3B” on page 252.
Correction of the Errata - See “Errata” on page 345.
This datasheet deals with product characteristics of AT90PW2 and AT90WM3. It will be updated as soon as
characterization will be done.
2. Disclaimer
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology. Min and Max val-
ues will be available after the device is characterized.
