how to define a byte variable in bit addressing space in assembly

chao lin over 22 years ago

Hi,

There is am assembly file that will be integrated into my project that is written in c. A variable defined in the assembly file as

PROCTOCOL  equ  020H

I converted it to

RSEG ?BI?RunIsp?ISP
?RunIsp?BIT:
PROTOCOL:  DBIT  8

The compiler gave me two errors:
1. DATA-ADDRESS EXPECTED
2. INVALID BYTE BASE IN BIT ADDRESS EXPRESSION

The first error was caused by

MOV	PROTOCOL, #0

and the second error was caused by

SETB	PROTOCOL^1

How should I define PROTOCOL to make it work in c environment? Thank you for answering my question.
