(3) When using a 17K series assembler (AS17K)
No error is output when an attempt is made to write the value 1 to a bit fixed at 0. The instruction shown
in
Example 1
MOV BANK, #0100B
will not cause an assembler error. However, when the instruction is executed in the in-circuit emulator, an
error is generated.
The assembler (AS17K) does not generate errors because it does not check the correspondence between
the symbol (including reserved words) and the data memory address which are the objects of the data memory
operation instruction. However, in the following case, the assembler generates an error:
When a value of 1 or more is given to "n" in the incorporation macro instruction "BANKn".
This is so because the assembler determine that no incorporation macro instructions other than BANK0 can
be used on the
