Does it need STATUS register in all banks?

Dear All,


https://www.electro-tech-online.com/threads/how-to-clean-execess-flux.527/

First I would like to thanks to Jon Wilder who wrote such grate lesson on PIC micro bank selection very clearly ( SEE above link)

As per above link says
If I say the STATUS register mapped to all banks not valid. Does it need STATUS register in all banks

Please advice

hi,

If the STATUS register address was not accessible from within ALL the BANKs, how would you be able to change BANKs, likewise with the PCL register.

Also your program always needs access to all the FLAGs in STATUS register

Is this what you mean.?

Yes you wouldnt be able to use instructions that use status bits, like decfsz so your code would be limited.
Nice one eric if you switched to page 1 and there wasnt an rp0 bit in page 1 how would you get back, A lightswitch that vanishes when you turn it on.
