Executes a trap, the value of the operand is used as the trap number, only #15 is supported. The register d0 will be used as the trap type which are:

Opcode	Description
0	Print string pointed by a1 with length read in d1.w, null terminated with max of 255, then prints a new line.
1	Print string pointed by a1 with length read in d1.w.
2	Read string from keyboard, writes the string at address of a1 and overrides the value of d1 with the length of the string.
3	Print signed number at d1.
4	Read number, writes to d1.
5	Read character, writes to d1.
6	Print character at d1.
8	Get time, writes to d1.
9	Terminate.
13	Prints null terminated string pointed by a1 then prints new line, errors if string is longer than 16kb, to prevent infinite loops.
14	Prints null terminated string pointed by a1, errors if string is longer than 16kb, to prevent infinite loops.
15	Prints unsigned number at d1 in base (from 2 to 36) specified in d2.b
23	Delays the execution of the simulator by milliseconds of the value in d1.
