Read shadow register - Omar - Jun 30 8:38:44 2008
Hello:
I need read the last status of a bit of port B. I write the bit ussing
this statement:
BitWrPortI(PBDR,&PBDRShadow,1,5);
I understand that need read the shadow register, because the port B is
write only.
But not found as I can read the bit 5 (in this case) form the
PBDRShadow. Is there an instruccion type BitRdxxxx of I should be read
the bit ussing an AND opperation ?.
If is of the last form, can you send an example ?
Thank you to all
Omar
