# sampling06 (or just sampling): Sample points for other modes
#
# sampling7: Sample points for mode 7
#
# These properties use a common syntax: an list of comma seperated numbers
# corresponding in order to the following parameters:
#
# ------- Range ------- --- Default Value ---
# Mode 0..6 Mode 7 Mode 0..6 Mode 7
# - All Offsets 0..5 0..7 0 0
# - A Offset 0..5 0..7 0 0

#
# Any number of these parameters can be specified but typically you would specify:
#
# - A single value: All Offsets (which sets Offsets A..F to that value)
# -- or --
# - 12 comma seperated values: 0,A,B,C,D,E,F,Half,Divisor,Mux,Delay,Sample Mode

# Here's a brief description of each of sampling parameter:
# - A Offset: set the sub-pixel sampling point for the 1st Pixel, 7th Pixel, etc.

# - For Mux use 0 (unless you have an Electron)
# - For Delay use the "Delay" value
# - For Sample Mode use 0
#

#
# Note: for CPLDv1, the H Offset defaults are 0 and 0
# Note: for CPLDv3, the H Offset defaults are 38 and 32
#
# Any number of these parameters can be specified but typically you would specify
# 7 comma seperated values:
# - H Offset,V Offset,H Width,V Height, FB Width, FB Height, FB Height x2
#
# Values outside of the ranges above may or may not work!
#
# Here's a brief description of each of sampling parameter:
# - H Offset: defines where to start capturing a line (units are 4-pixels)
