#
# The other settings are less obvious, since the definitions of the SSD1963 data sheet and the
# LCD data sheets differ. So what' common, even if the names may differ:
# HDP  Horizontal Panel width (also called HDISP, Thd). The value store in the register is HDP - 1
# VDP  Vertical Panel Width (also called VDISP, Tvd). The value stored in the register is VDP - 1
# HT   Total Horizontal Period, also called HP, th... The exact value does not matter
# VT   Total Vertical Period, alco called VT, tv, ..  The exact value does not matter
# HPW  Width of the Horizontal sync pulse, also called HS, thpw.
# VPW  Width of the Vertical sync pulse, also called VS, tvpw
# Front Porch (HFP and VFP) Time between the end of display data and the sync pulse
# Back Porch (HBP  and VBP Time between the start of the sync pulse and the start of display data.
#      HT = FP + HDP + BP  and VT = VFP + VDP + VBP (sometimes plus sync pulse width)
# Unfortunately, the controller does not use these front/back porch times, instead it uses an starting time
# in the front porch area and defines (see also figures in chapter 13.3 of the SSD1963 data sheet)
# HPS  Time from that horiz. starting point to the start of the horzontal display area
# LPS  Time from that horiz. starting point to the horizontal sync pulse
# VPS  Time from the vert. starting point to the first line
# FPS  Time from the vert. starting point to the vertical sync pulse
#
# So the following relations must be held:
#
# HT >  HDP + HPS
# HPS >= HPW + LPS
# HPS = Back Porch - LPS, or HPS = Horizontal back Porch
# VT > VDP + VPS
# VPS >= VPW + FPS
# VPS = Back Porch - FPS, or VPS = Vertical back Porch
#
# LPS or FPS may have a value of zero, since the length of the front porch is detemined by the
# other figures
#
# The best is to start with the recomendations of the lCD data sheet for Back porch, grab a
# sync pulse with and the determine the other, such that they meet the relations. Typically, these
# values allow for some ambuigity.
