Description
2k_8k_from_DPLL2
Register to select the source (DPLL1 or DPLL2) for
the 2 kHz and 8 kHz outputs available from O1 and
O2.
Not used.
8k_invert
Register bit to invert the 8 kHz output from FrSync.
8k_pulse
Register bit to enable the 8 kHz output from FrSync
to be either pulsed or 50:50 duty cycle. Output 02
must be enabled to use “pulsed output” mode on
the FrSync output, and then the pulse width on the
FrSync output will be equal to the period of the
output programmed on O2.
2k_invert
Register bit to invert the 2 kHz output from
MFrSync.
2k_pulse
Register bit to enable the 2 kHz output from
MFrSync to be either pulsed or 50:50 duty cycle.
Output 03 must be enabled to use “pulsed output”
mode on the MFrSync output, and then the pulse
width on the MFrSync output will be equal to the
period of the output programmed on O3.
