TRAP #15 Functions

An additional utility within the dBUG firmware is a function called the TRAP 15 handler. This function
can be called by the user program to utilize various routines within the dBUG, to perform a special task,
and to return control to the dBUG. This section describes the TRAP 15 handler and how it is used.

There are four TRAP #15 functions. These are: OUT_CHAR, IN_CHAR, CHAR_PRESENT, and
EXIT_TO_dBUG.

2.5.1.

OUT_CHAR

This function ( function code 0x0013) sends a character, which is in lower 8 bits of D1, to terminal.

Assembly example:

/* assume d1 contains the character */
move.l

#$0013,d0

Selects the function

TRAP

#15

The character in d1 is sent to terminal

C example:

void board_out_char (int ch)
{

/* If your C compiler produces a LINK/UNLK pair for this routine,
* then use the following code which takes this into account
*/

#if l

/* LINK a6,#0 -- produced by C compiler */
asm (“ move.l

8(a6),d1”);

/* put ‘ch’into d1 */

asm (“ move.l

#0x0013,d0”); /* select the function */

asm (“ trap

#15”);

/* make the call */

/* UNLK a6 -- produced by C compiler */

#else

/* If C compiler does not produce a LINK/UNLK pair, the use
* the following code.
*/
asm (“ move.l 4(sp),d1”);

/* put ‘ch’into d1 */

asm (“ move.l

#0x0013,d0”); /* select the function */

asm (“ trap

#15”);

/* make the call */

#endif
}

2.5.2.

IN_CHAR

This function (function code 0x0010) returns an input character (from terminal) to the caller. The returned
character is in D1.
