-/* Be wary: the lower N bits of the *address* of the function
- determines the syscall used by the simulator. Thus, the addresses
- listed here depend on the syscall numbers in ../syscalls.h. */
-
-/* As per the MSP430x200 Family Users Guide, section 1.5, "An
- instruction fetch from the address range 0x0000 - 0x01FF will reset
- the device." We take advantage of that to do syscalls in the
- simulator, by trying to execute specific addresses in that range
- and letting the simulator catch them while simulating the CALL
- instruction. In theory, this is an operation that the physical
- hardware will never attempt to do, so it won't interfere with the
- simulation's accuracy (i.e. we aren't abusing holes in the opcode
- map, for example). */
