Description
Task AVBI Even Base Address. This register specifies the base address in graphics
memory where VBI data for even fields is stored. Changes to this register take effect at
the beginning of the next field. The value in this register is 16-byte aligned. This value
needs to be 32-byte aligned. (Bits [4:0] are required to be 00000.)
Note: This register is double buffered. When a new value is written to this register, the
new value is placed in a special pending register, and the Base Register Not Updated bit
(VIP Memory Offset 08h[16]) is set to 1. The Task A VBI Even Base Address register is
not updated at this point. When the first data of the next field is captured, the pending val-
ues of all base registers are written to the appropriate base registers, and the Base Reg-
ister Not Updated bit is cleared.
Description
Task A VBI Odd Base Address. This register specifies the base address in graphics
memory where Task A VBI data for odd fields are stored. Changes to this register take
effect at the beginning of the next field. The value in this register is 8-byte aligned. This
value needs to be 32-byte aligned. (Bits [4:0] are required to be 00000.)
Note: This register is double buffered. When a new value is written to this register, the
new value is placed in a special pending register, and the Task A Base Register Not
Updated bit (VIP Memory Offset 08h[16]) is set to 1. The Task A VBI Odd Base Address
register is not updated at this point. When the first data of the next field is captured, the
pending values of all base registers are written to the appropriate base registers, and the
Base Register Not Updated bit is cleared.
