Registers used by ''DispVram'' State object to control overexposure highlighting feature.

===Note on directly writing the registers===

Some models overwrite register values with ones stored in memory. For example, 750D.110 does that for enable register, 200D.101 overwrites both enable and style regs, EOS R does that only for HDMI enable register (see [[digic8:registers|Digic 8 Registers]]). Reason is not yet known, but in those cases one needs to update in-ram value instead of given register directly.

===Enable register===

''reg & 0x10000000'' controls if highlight is enabled or not.

===Threshold / style register===

<code>
**** **** **** **** **** **** **** ****
*... .... .... .... .... .... .... .... visibility (on/off)
.... .... *... .... .... .... .... .... stripes angle (45 / -45 deg)
.... .... .*.. .... .... .... .... .... stripes move speed (0-1)
.... .... ..** .... .... .... .... .... stripes style
.... .... .... .*** .... .... .... .... stripes opacity
.... .... .... .... **** **** .... .... threshold (underexpo)
.... .... .... .... .... .... **** **** threshold (overexpo)
</code>

| speed        | 0-1   | lines/dots are moving slower -> faster                  |
| style        | 0-3   | 0: light dots, 1: thin lines, 2: thick lines, 3 = 0     |
