i am finding some other issues with bank access with other asm code i have , that is not happy on q43

thinking that what you did with
-----------
movf BSR, 0
banksel INT_Priority_Reg
bsf INT_Priority_Reg, INT_Priority_Bit
movwf BSR
-----------

historic code i use for elasped timer to get the cycles constant and limited may now work against q43 chip ??

i may be wrong as my asm really sucks but each command that has BCF will need a banksel , bsf ????

having trouble with load of timer1 using asm on the q43

but doing that change would add cycles i am sure

i hope i am wrong


Code:
 ASM
                                 ; 16.368mhz tcxo = 61.0948ns clock       16.00Mhz = 62.5 ( internal osc used currenlty 20/2/20)
TimerConst = 40912               ; 40912 + 8 cycle instrution load = 40920 x 61.0948ns = 2.499999216mS  timer 1 clock tick   (  16mhz int = 39992 + 8cycle = 40000 x 62.5ns = 2.5ms) 
TimerConst = 65536 - TimerConst  ; set value for timer1 preload
