Hi there I am using a 74A for some async TX/RX and would like to know what the best way of configuring BRGH is? Either high speed or low speed as I understand that there is a bug in one of the settings. I also wrote some code and ran it in the MPLAB ver 3.22.02. The code is for the 74A is as follows: ORG 00H BSF STATUS,RP0 CLRF TRISA CLRF TRISE BCF STATUS,RP0 BSF PORTA,0 BSF PORTA,1 BSF PORTA,4 BSF PORTE,0 END Non of these instructions seem to set the bits, or that's what the simulator indicates. The only bit which sets is Port A bit 4. Is it something to do with their alternate functions? Thanks in advance Gavin vulcan@ihug.co.nz
