Main Window Display Start Address Bits [16:0]
This register specifies the starting address, in DWORDS, for the LCD image in the display
buffer for the main window.
Note that this is a double-word (32-bit) address. An entry of 00000h into these registers
represents the first double-word of display memory, an entry of 00001h represents the sec-
ond double-word of the display memory, and so on. Calculate the Display Start Address as
follows:
Main Window Display Start Address bits 16:0
= image address ÷ 4 (valid only for SwivelView 0°)
Note
For information on setting this register for other SwivelView orientations, see Section
12, “SwivelView™” on page 138.
