0003 KernelVersion: 2.6.37
0004 Contact: linux-iio@vger.kernel.org
0005 Description:
0006 Stores frequency into tuning word Y.
0007 There will be more than one out_altvoltageX_frequencyY file,
0008 which allows for pin controlled FSK Frequency Shift Keying
0009 (out_altvoltageX_pincontrol_frequency_en is active) or the user
0010 can control the desired active tuning word by writing Y to the
0011 out_altvoltageX_frequencysymbol file.

0014 KernelVersion: 2.6.37
0015 Contact: linux-iio@vger.kernel.org
0016 Description:
0017 Scale to be applied to out_altvoltageX_frequencyY in order to
0018 obtain the desired value in Hz. If shared across all frequency
0019 registers Y is not present. It is also possible X is not present
0020 if shared across all channels.

0025 Description:
0026 Specifies the active output frequency tuning word. The value
0027 corresponds to the Y in out_altvoltageX_frequencyY.
0028 To exit this mode the user can write
0029 out_altvoltageX_pincontrol_frequency_en or
0030 out_altvoltageX_out_enable file.

0035 Description:
0036 Stores phase into Y.
0037 There will be more than one out_altvoltageX_phaseY file, which
0038 allows for pin controlled PSK Phase Shift Keying
0039 (out_altvoltageX_pincontrol_phase_en is active) or the user can
0040 control the desired phase Y which is added to the phase
0041 accumulator output by writing Y to the phase_en file.

0046 Description:
0047 Scale to be applied to out_altvoltageX_phaseY in order to obtain
0048 the desired value in rad. If shared across all phase registers
0049 Y is not present. It is also possible X is not present if
0050 shared across all channels.

0055 Description:
0056 Specifies the active phase Y which is added to the phase
0057 accumulator output. The value corresponds to the Y in
0058 out_altvoltageX_phaseY. To exit this mode the user can write
0059 out_altvoltageX_pincontrol_phase_en or disable file.

0066 Description:
0067 out_altvoltageX_pincontrol_en: Both, the active frequency and
0068 phase is controlled by the respective phase and frequency
0069 control inputs. In case the device in features independent
0070 controls, then there are dedicated files
0071 (out_altvoltageX_pincontrol_frequency_en,
0072 out_altvoltageX_pincontrol_phase_en).

0078 Description:
0079 out_altvoltageX_outY_enable controls signal generation on
0080 output Y of channel X. Y may be suppressed if all channels are
0081 controlled together.
