attiny1634 and serial communication (BUG in attiny1634 ?)

Hi,

i encounter a problem when trying to

config com1=9600, synchrone=0,parity = none,stopbits=1,databits=8,clockpol=0

I get a compile error :

.EQU not found, probably using functions that are not supported by the selected chip [UCSRC]

There are also errors if i try to :

config serial = buffered, size=20

saying interrupt USRX not found.

When i search attiny1634.dat i cannot find USRX, also no USRC ...

Any suggestions ?

According to the datasheets, tiny1634 and mega162 are using the same USART structure.
If I compile my prog with regfile m162def.dat, i dont get any error. So to me, it seems there's an error in the

attiny1634.dat,

but i don't know how to fix it ....

thx in advance

Good to know. I am right now preparing a PCB for using Attiny1634. So I should postpone it until a fix has been found...
In the dat files there is a difference:

search for :
UCSR0C = $24
and add this below :
UCSRC = $24

or simply change the ucsr0c into ucsrc

also the INT section must look like this :

Hello,

Sorry for the late reply on that subject, but I have a project with Attiny1634 and I can´t find the attiny1634.dat file under BASCOM folder. I am using DEMO 2.0.7.5 version. Is this file only available in full BASCOM version?

Best Regards,
