Hi,
my problem:
I transmit at 115200 Baud and have to set also the parity bit TXSTA
->Bit0(TXD9) Bank1 / odd Parity.
I wrote the code for setting the bit and it works fine until speeds of
19.200 Baud but not for higher speeds!
I found out that the bank switching to set bit TXD9 (bank1) disturbes
the code.
Here a chunk of the code:

 movfw  STATUS       ; this chunk of code saves the current status, then

 movf   s_temp,w     ; clears STATUS reg and switches to bank 1
 bcf    flagbyte,3   ; clear parity indication LED (for status
display...)
 clrf   STATUS
 bsf    STATUS,RP0   ; switch to bank 1
 bcf    TXSTA,TX9D   ;  clear parity bit
 bcf    STATUS,RP0   ; switch to bank 0
 movf   s_temp,w     ; restore STATUS reg
 movwf  STATUS       ;
 goto   txnrd        ; jump to transmission code


the red colored lines are the cause for the malfunction! As soon as I
comment them out
al works nice!
But I need to switch to bank 1 or not?
Any help wellcome..
