Bt848/848A/849A
Single-Chip Video Capture for PCI
Horizontal Active Register, Lower Byte
Memory Mapped Location 0x01C – Even Field (E_HACTIVE_LO)
Memory Mapped Location 0x09C – Odd Field (O_HACTIVE_LO)
Upon reset it is initialized to 0x80. HACTIVE_LO(0) is the least significant bit. HACTIVE defines the number of hor-
izontal active pixels per line output by the Bt848. This 8-bit register is the lower byte of the 10-bit HACTIVE register.
The two MSBs of HACTIVE are contained in the CROP register.
Horizontal Scaling Register, Upper Byte
Memory Mapped Location 0x020 – Even Field (E_HSCALE_HI)
Memory Mapped Location 0x0A0 – Odd Field (O_HSCALE_HI)
Upon reset it is initialized to 0x02. This 8-bit register is the upper byte of the 16-bit HSCALE register.
Horizontal Scaling Register, Lower Byte
Memory Mapped Location 0x024 – Even Field (E_HSCALE_LO)
Memory Mapped Location 0x0A4 – Odd Field (O_HSCALE_LO)
Upon reset it is initialized to 0xAC. This 8-bit register is the lower byte of the 16-bit HSCALE register.
