Hi Don,Originally Posted by dbachman
PortB.3 is in the lower 4 bits you are using, you might think good thoughts of moving the E bit to b.4 and then you can address the lower bits as individuals or read the entire port and mask out the upper bits after reading them.

Hi Joe,
I did do something like that. I moved it to Porta bit 7. Just sittin there anyway. How do you read the entire port - better yet, how would you masked out the bits. I am still in a steep learning curve so please bear with me. Is it like this?
DTMF = DTMF & %00001111 ' isolate lower 4 bits
Thanks, Don
