Control Definition
Base Address Selector The indirect registers use a 24-bit address internally. The base address selector
allows quick entry of the base address. The list contains base addresses for the
major functional blocks of the TVP5160 decoder.
Base Address Edit Box This allows the 24-bit base address to be typed in directly.
Address Offset Edit Box This contains the lowest byte of the 24-bit internal address. The full 24-bit address
is formed by adding the base address to the address offset.
The address up/down arrows increment/decrement the address offset by 4.
Data Edit Boxes This contains the 32-bit data word that will be written to or read from the indirect
address. The LSB data is at the lowest address. The data is written/read LSB first.
The data up/down arrows increment/decrement the data value by 1.
Write Button Writes the (4) bytes in the Data Edit boxes starting at the 24-bit indirect address
BASE+OFFSET.
Read Button Reads (4) consecutive data bytes starting at the 24-bit indirect address
BASE+OFFSET to the Data Edit boxes.
Loop Count Edit Box Causes subsequent write or read operations to be performed N times. N is
entered as a decimal number from 1 to 999.
Close Button Closes the dialog.
NOTE: The indirect register editor can remain open with other windows. Use the
Window menu to navigate.
