Video Mode 0 Register (VM0)
Write address = 00H, read address = 80H.
Read/write access: unrestricted.
To write to this register, the following conditions must
be met:
1) STAT[5] = 0, the character memory (NVM) is not
busy.
2) DMM[2] = 0, the display memory (SRAM) is not
in the process of being cleared.

Sync Select Mode (Table 1)
0x = Autosync select (external sync when LOS = 0 and internal sync when LOS = 1)

0 = Off
1 = On

Vertical Synchronization of On-Screen Data
0 = Enable on-screen display immediately
1 = Enable on-screen display at the next VSYNC
10
Software Reset Bit
When this bit is set, all registers are set to their default values and the display memory is cleared.
When a stable 27MHz clock is present, this bit is automatically cleared internally after typically
100s. The user does not need to write a 0 afterwards. SPI operations should not be performed
during this time or unpredictable results may occur. The status of the bit can be checked by
reading this register after typically 100s. This register is not accessible for writing until the display
memory clear operation is finished (typically 20s).
00
Video Buffer Enable
0 = Enable
1 = Disable (VOUT is high impedance)
X = Don’t care.
