CONTROL DEFINITION
Base Address Selector The hardware registers use a 10-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
TVP5154.
Address Offset Edit Box Contains the lowest byte of the 10-bit internal address. The full 10-bit address is formed by adding
the base address to the address offset. The address up/down arrows increment/decrement the
address offset by 1.
Data Edit Boxes Contains the 16-bit data word that is written to or read from the register 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 (2) bytes in the data edit boxes starting at the 10-bit register address BASE+OFFSET.
Read Button Reads (2) consecutive data bytes starting at the 10-bit register 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.

Note: The memory map editor can remain open with other
windows. Use the Window menu to navigate.
The property sheets represent the register data in a user-friendly format. The data is organized by
function, with each function having its own page and being selectable via tabs at the top (see Figure 20 ).
To open this, click on Edit Property Sheets in the Edit menu and select the device type to edit.
When the property sheet function is started or whenever the user tabs to a different page, all readable
registers in the device are read from hardware to initialize the dialog pages. Values on the page are
changed by manipulating the various dialog controls as described in Table 6 .
OK, Cancel, and Apply buttons are at the bottom of each property page. These are described in Table 7 .
