PRELIMINARY SPECIFICATION
When set to 1, EVO features are enabled. When set to 0 (the hardware reset value), the EVO
behaves exactly like a TM-1000 VO unit. Default: 0.
Activates full 8-bit alpha blending when set to 1. When set to 0, only the original five TM-1000
blending levels are implemented (0%, 25%, 50%, 75%, 100%). Default: 0.
TM-1000 default values (240 and 16 for Y, U and V) are used. Default: 0.
7.18.2, “Data-transfer
When set, VO_IO2 will generate frame synchronization signal that follows the field number in
SAV/EAV codes (Field1 gives a low VO_IO2, Field2 gives a high VO_IO2). Default: 0.
Activates Genlock mode when set to 1 and VO_CTL. SYNC_MASTER = 0. Default: 0.
When set, this bit activates chroma key. The overlay values (Y, U and V) are compared to the val-
ues stored in the EVO_KEY register. Bits that correspond to bits set in MASK_Y and MASK_UV
are ignored for the comparison. When there is an exact match between the pixel value and the
value in EVO_KEY register (less the bits selected by MASK_Y and MASK_UV), then the overlay
value is not present in the output stream, resulting in full transparency.
The key is 24 bits (Y, U and V are 8 bits each). Default: 0.

KEY_V
The hardware reset value of EVO_CTL register is
0x10000000, which means that EVO functions are dis-
abled on reset and must be enabled by software. The MS
four bits indicate the EVO revision number.
To ensure compatibility with future devices, any unde-
fined MMIO bits should be ignored when read, and writ-
ten as ‘0’s.
