Disables or enables and sets the frequency of the 4-bit programmable frequency output.

FOUT_port is the frequency output port to be programmed.

1:

For FOUT1 on the PC-TIO-10 or FOUT on the MIO device, except the E Series 
devices.

2:

For FOUT2 on the PC-TIO-10.

mode selects whether to enable or disable the programmable frequency output. mode can be 
0 or 1.

0:

The frequency output signal is turned off to a low-logic state.

1:

The frequency output signal is enabled.

If mode = 0, none of the following parameters apply.

timebase selects the timebase, or resolution, to be used by the programmable frequency 
output. timebase has the following possible values:

–1:

Internal 5 MHz clock used as timebase (200 ns resolution) (AT-MIO-16F-5, 
AT-MIO-64F-5, AT-MIO-16X, and PC-TIO-10 only).

1:

Internal 1 MHz clock used as timebase (1 µs resolution).

2:

Internal 100 kHz clock used as timebase (10 µs resolution).

3:

Internal 10 kHz clock used as timebase (100 µs resolution).
