I have read in the ADuC832's datasheet that the SFRs P2 and P3 are bit addressable, but the evaluation version of uVision2 doesn't allow to do it (I have a syntax error when I use - for example - the code line P2.3 =0x03) Is it a problem related to an incorrect code or does it depend from the fact that I have an uVision2's evaluation version? The full version of uVision2 allow to address bit by bit the SFRs P2 and P3?
"Is it a problem related to an incorrect code" Yes, it is. Your syntax is wrong - check the Manual for the correct Keil-specific 'C' syntax extension.
Ok! Thank you! I have already started reading the Cx51 Compiler's manual supplied with uVision2!
Beautiful! I have solved my problem, but not reading the manual!!!! I have opened some files of the Analog Devices! Thank you for all!
