DOT[15:8] — OSD FLASH Even High Byte Buffer
The OSDEHBUF register is a buffer for temporarily storing the even byte
(or high byte) of an OSD font line to be programmed to the OSD FLASH
memory. A 16-bit OSD font line is programmed by writing the even byte
to OSDEHBUF, followed by a FLASH programming routine to the odd
byte in the font memory. Programming the odd byte will automatic
program the even byte. See
OSD font memory map and
programming.

Read:
Write:
These bits define the even byte for a single line of OSD font, to be
programmed to the OSD FLASH memory. Reset has no effect on
these bits.
