HG		 22/* Some documentation about various registers as determined by trial and error.
23 When the register addresses differ between the 7202 and the 7311 the 2
24 different addresses are written as 7302addr/7311addr, when one of the 2
25 addresses is a - sign that register description is not valid for the
26 matching IC.
27
28 Register page 1:
29
30 Address Description
31 -/0x08 Unknown compressor related, must always be 8 except when not
32 in 640x480 resolution and page 4 reg 2 <= 3 then set it to 9 !
33 -/0x1b Auto white balance related, bit 0 is AWB enable (inverted)
34 bits 345 seem to toggle per color gains on/off (inverted)
35 0x78 Global control, bit 6 controls the LED (inverted)
36 -/0x80 JPEG compression ratio ? Best not touched
37
38 Register page 3/4:
39
40 Address Description
41 0x02 Clock divider 2-63, fps =~ 60 / val. Must be a multiple of 3 on
038ec7c7 42 the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
327c4abf
HG		 43 -/0x0f Master gain 1-245, low value = high gain
44 0x10/- Master gain 0-31
45 -/0x10 Another gain 0-15, limited influence (1-2x gain I guess)
46 0x21 Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
8a5b2e90
HG		 47 -/0x27 Seems to toggle various gains on / off, Setting bit 7 seems to
48 completely disable the analog amplification block. Set to 0x68
49 for max gain, 0x14 for minimal gain.
