Dsp_Hf1()                                                             XBIOS

Syntax

WORD Dsp_Hf1( flag )
WORD flag;

Function      Dsp_Hf1() reads/writes to bit #4 of the HSR.

Opcode        120 (0x78)

Availability  Available only when bit #3 of the '_SND' cookie is set.

Parameters    flag has three legal values as follows:

              Name       flag   Meaning

              HF_CLEAR     0    Clear bit #4 of the DSP's HSR.

              HF_SET       1    Set bit #4 of the DSP's HSR.

              HF_INQUIRE  -1    Return the current value of bit #4 of the
                                DSP's HSR.

Binding       move.w   flag,-(sp)
              move.w   #$78,-(sp)
              trap     #14
              addq.l   #4,sp

Return Value  If flag is HF_INQUIRE (1), Dsp_Hf1() returns the current
              state of bit #4 of the HSR register.
