PLL active, AMCLK is field-locked
PLL open, AMCLK is free-running
vertical reference pulse is taken from internal decoder
vertical reference is taken from XRV input (expansion port)
ALRCLK edges triggered by falling edges of ASCLK
ALRCLK edges triggered by rising edges of ASCLK
ASCLK edges triggered by falling edges of AMCLK
ASCLK edges triggered by rising edges of AMCLK
Hamming check for 2 bytes after framing code,
dependent on data type (default)
no Hamming check
one framing code error allowed
no framing code errors allowed
amplitude searching active (default)
amplitude searching stopped
