Configuring Portmux for TCB0/1

Good day,

I have been trying to configure Portmux to use the WO´s of TCB0 and TCB1 on a MEGAX4809, i am running BASCOM AVR 2.0.8.7. Before going into writing into the registers by myself, i wanted to ask what i am doing wrong :

Looking at documentation and datasheet this would be sufficient information IMHO :

I think there is a typo in the DAT file.

I think in the lines:
3386 there is PORTMUX_TCAROUTEB but should be PORTMUX_TCBROUTEA
3389 there is PORTMUX_TCAROUTEB but should be PORTMUX_TCBROUTEA

DAT files you can watch and edit in any text editor or even Bascom if you have in Options->Environment->Editor->No reformat files "DAT"

It seems there is an error in the DAT file for the [PORTMUX]

OPTION19=TCB0
OPTION19VALUE=[DEFAULT_PA2,ALT_PF4]
OPTION19DATA=[PORTMUX_TCAROUTEB,5,xxxx1110,0,1]

change :

OPTION19=TCB0
OPTION19VALUE=[DEFAULT_PA2,ALT_PF4]
OPTION19DATA=[PORTMUX_TCBROUTEA,5,xxxx1110,0,1]
OPTION20=TCB1
OPTION20VALUE=[DEFAULT_PA3,ALT_PF5]
OPTION20DATA=[PORTMUX_TCBROUTEA,5,xxxx1101,0,1]
OPTION21=TCB2
OPTION21VALUE=[DEFAULT_PC0,ALT_PB4]
OPTION21DATA=[PORTMUX_TCBROUTEA,5,xxxx1011,0,1]
OPTION22=TCB3
OPTION22VALUE=[DEFAULT_PB5,ALT_PC1]
OPTION22DATA=[PORTMUX_TCBROUTEA,5,xxxx0111,0,1]

also put them in 1 line :

Thanks both for your swift and proper reply.

This compiles without errors now.
