Holtek HT48R30A-1 User Manual

The following source program refers to the macro Delay:
The Cross Assembler will expand the macro Delay as shown in the following listing file. Note that
the offset of each line in the macro body, from line 4 to line 17, is 0000. Line 24 is expanded to 11
lines and forms the macro body. In addition the formal parameters, tmp1 and tmp2, are replaced
with the actual parameters, BCnt and SCnt, respectively.
