C. DIFFERENCES BETWEEN THE PMC-SC
AND THE PMC-N, AND HOW TO
MIGRATE FROM THE PMC-N/NA TO
THE PMC-SC/SC3/SC4/NB/NB2
APPENDIX
485
(1) For the PMC-SC/SC3/SC4/NB/NB2, any integer from 10 to 99 can
be specified for the priority of a task.
(2) The task priorities can be changed during execution of the user
program.
The Link Control Statement for the PMC-SC/SC3/SC4/NB/NB2 is
created using the tool for creating the Link Control Statement.
[Limitations on use of the IC-286 compiler]
(1) Referencing by physical addresses is not allowed.
(2) The characters “const” must be attached to constants. Otherwise the
constants are placed in the ROM area.
(3) For compilation of an array of structures, the number of the structures
must be even.
(4) When specifying the pointer to a structure, its member names must
not be omitted.
(5) When an immediate value is specified in an argument of data type
“long”, the cast (long) must be attached to the argument.
(6) An element of data type “int” is two-bytes long.
(7) When data redefined by UNION is operated on by specifying the
compile option OPTIMIZE=3, the result of the operation may be
incorrect.
