 		 #123069 - Stack
Responding to: ???'s previous message
Dear Joseph,

Here is the point that makes me confuse

Save This Code
?STACK          SEGMENT   IDATA

                RSEG    ?STACK
                DS      1


I don't really get this. In this case, is 1 byte reserved for for Stack or a variable name ?Stack and its function is to point to Stack? Furthermore, the STARTUP1 section seems to clear everything from 0x00 to 0x3f of data memory (the MCU I'm currently using has only 64 bytes of data memory). In this case I think it overwrites Stack. Am I wrong? If I understand correctly, at power on by default SP is at 0x07 and the STARTUP1 will clear this value. In this case how do I know the value of SP. Please explain this for me. Thank you in advance.

Best regards,
T.L
