Hello All, Writing my first code for a PC16C74A - the data book indicates that I need to take care of PCLATH<3> when using CALL or GOTO beyond the 2k boundary, and further states that I don't need to worry about it on RETURN... I've found that to be incorrect, at least when running MPSIM... is this an MPSIM bug? or a mistake in the data book? Thanks! Bob
