When I write the following in uVision,
mov A, -2000
I want A to contain 0x30, as -2000 is 0xF830. Instead it contains 0x05. Is there any predefined macro to be able to treat a literal as sixteen bits and extract the lower (or upper) eight bits out of it?
Thanks.
More of an expression than a macro. It's in the manual.
HIGH and LOW, IIRC.
