Description
Reserved.
Blink Count. These bits provide a real-time blink counter value. This register is not syn-
chronized to the system clock domain.
Description
VGALatchSavRes. This register is used to save/restore the 32-bit VGA data latch.
When the CRTC index register is written, an internal byte counter is cleared to 0. Four
successive reads or writes to the CRTC data register at this index will return or write
bytes 0 (bits [7:0]), 1 (bits [15:8]), 2 (bits [23:16]), then 3 (bits [31:24]) in sequence.
Description
DACIFSavRes. This register is used to save/restore the VGA palette interface logic
state. When the CRTC index register is written, an internal byte counter is cleared to 0.
Four successive reads or writes to the CRTC data register at this index will return or write
bytes 0 (bits [7:0]), 1 (bits [15:8]), 2 (bits [23:16]), then 3 (bits [31:24]) in sequence.
