DAI12-4(FIT)GY

- Output mode [D2]:

This step sets the specific D/A conversion output method to be employed.
Two output methods are available: "transparent mode", in which analog outputs from
channels are updated in arbitrary, software-based timing; and "synchronous output
mode", in which the analog outputs from multiple channels are simultaneously
updated in arbitrary, software-based timing.

Output Mode

[0] : Transparent

* Initialized state

[1] : Synchronous output

- Pacer clock [D1]:

This option is set only if the clock mode is selected as a D/A conversion mode.

Pacer Clock

[0] : Internal Pacer Clock

* Initialized state

[1] : Reserved

- D/A conversion mode [D0]:

This step sets the timing for D/A conversion output.
Two sampling modes are supported:    "software mode", in which analog output is
produced from a software-specified channel; and "clock mode", in which periodic
D/A conversions are performed by means of clock signals.

Sampling Mode

[0] : Software Command * Initialized state

[1] : Clock

Following are examples in which D/A conversion conditions are specified in high-level

languages:

Microsoft C

Microsoft QBASIC

outp( ADR+24, 0x2 );

OUT ADR+24, &H2

outp( ADR+28, ConditionData );

OUT ADR+28, ConditionData
