Second revision of parts, for all new developments.
The major changes are :
• complement the PSCOUT01, PSCOUT11, PSCOUT21 polarity in
centered mode -
Aligned Mode" on page 139.
• Add the PSC software triggering capture -
Register – PICR0H and PICR0L" on page 170.
AT90PWM2B
• Add bits to read the PSC output activity -
AT90PWM3B
Register – PIFR0" on page 172.
• Add some clock configurations -
AT90PWM2B/3B" on page 31.
• Change Amplifier Synchonization -

• Correction of the Errata -
This datasheet deals with product characteristics of AT90PW2 and AT90WM3. It will be updated
as soon as characterization will be done.
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.
