-===== DIGIC 8 Register Map: =====
-==== UART ====
-Controls physical UART connections.
-^ Address        ^ Description     ^
-| ''0xD01202F0'' | UART1_RX_SELECT |
-| ''0xD01202F4'' | UART1_TX_SELECT |
-| ''0xD01302F0'' | UART2_RX_SELECT |
-| ''0xD01302F4'' | UART2_TX_SELECT |
-''UART2'' is unknown.
-''UART1'' is connected to physical ICU UART on external debug connector. Handled by ''uart_change'' command on drysh.
-''0x0'' selects ICU (DryOS on ARM core), ''0x2'' for CCLIME (DryOS on Xtensa core, network).

-| ''0xD0304488'' | LCD/EVF control register  |
-| ''0xD030448C'' | LCD/EFV related register  |
-| ''0xD0300750'' | HDMI control register     |
-| ''0xD0300754'' | HDMI related register     |
-Registers used by ''DispVram'' State object to control overexposure highlighting feature.
-Control register sets highlight params like threshold, color, style.
-Related register meaning is unknown at the moment, but it is also written on enable/disable by ''DispVram''
-At this moment we don't know how to enable highlights by just writing the registers. But while those are displayed - writing random number to control register changes both style and threshold of highlights.
-==== Audio ====
-^ Address         ^ Description                     ^
-| ''0xD800021D '' | Left Microphone Level and Peak  |
-| ''0xD8000220 '' | Right Microphone Level and Peak |
