UPSD 33xx Timers

Looking at the specs of the uPSD32xx series and I notice that the ART

baud rates are still determined by either timer 1 or 2. If different baud rates are required then 2 timers are committed leaving just timer 0 free for other functions.

In the uPSD33xx series does this restriction still apply? We currently

use another maufacturers device which have independent and separate baud rate generators for the UARTs which means that all three general timers are still free and in a most of our applications this is very important.

Please advise

I found a preliminary datasheet using Google (it's also posted in another thread on this forum):

Based on a quick scan, it looks like there are no new baud rate generators, except for some IrDA capabilities.
