VPP Map

The video postprocessor (VPP) map contains registers that

control the I2P core (interlaced-to-progressive converter).

The VPP map has a programmable I2C slave address, which is

programmed using Register 0xFD in the user sub map of the

main map. The default value for the VPP map address is 0x00;

however, the VPP map cannot be accessed until the I2C slave

address is reset. The recommended I2C slave address for the

VPP map is 0x84.

To reset the I2C slave address of the VPP map, write to the

VPP_SLAVE_ADDRESS[7:1] bits in the main register map

(Address 0xFD[7:1]). Set these bits to a value of 0x84 (I2C

write address; I2C read address is 0x85).

CSI Map (ADV7280-M Only)

The CSI map contains registers that control the MIPI CSI-2

output stream from the ADV7280-M.

The CSI map has a programmable I2C slave address, which is

programmed using Register 0xFE in the user sub map of the

main map. The default value for the CSI map address is 0x00;

however, the CSI map cannot be accessed until the I2C slave

address is reset. The recommended I2C slave address for the

CSI map is 0x88.

To reset the I2C slave address of the CSI map, write to the

CSI_TX_SLAVE_ADDRESS[7:1] bits in the main register map

(Address 0xFE[7:1]). Set these bits to a value of 0x88 (I2C write

address; I2C read address is 0x89).

SUB_USR_EN Bits, Address 0x0E[6:5]

The ADV7280/ADV7280-M main map contains three sub maps:

the user sub map, the interrupt/VDP sub map, and User Sub Map 2

(see Figure 14). The user sub map is available by default. The other

two sub maps are accessed using the SUB_USR_EN bits. When

programming of the interrupt/VDP map or User Sub Map 2 is

completed, it is necessary to write to the SUB_USR_EN bits to

return to the user sub map.
