Description
SIG_VALUE (Signature Value). (Read Only) A 24-bit signature value is stored in this bit field and can be read at any time.
The signature is produced from the RGB data output of the mixer. This bit field is used for test purpose only.
See SIGN_EN (bit 0) description for more information.
Reserved.
SIGN_FREE (Signature Free Run).
0: Disable. (Default) If this bit was previously set to 1, the signature process stops at the end of the current frame (i.e., at
1: Enable. If SIGN_EN (bit 0) = 1, the signature register captures data continuously across multiple frames.
Reserved.
SIGN_EN (Signature Enable).
0: Disable. (Default) The SIG_VALUE (bits [31:8]) is reset to 000001h and held (no capture).
1: Enable. The next falling edge of VSYNC is counted as the start of the frame to be used for CRC checking with each pixel
After a signature capture, the SIG_VALUE can be read to determine the CRC check status. SIGN_EN can then be reset to
initialize the SIG_VALUE as an essential preparation for the next round of CRC check.

REV_ID (Revision ID). See the AMD Geode™ SC1200/SC1201 Processor Specification Update document for value.
DEV_ID (Device ID). See AMD Geode™ SC1200/SC1201 Processor Specification Update document for value.
Reserved.
ALPHA3_WIN_PRIORITY (Alpha Window 3 Priority). Determines the priority of Alpha Window 3. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha windows.
00: Lowest priority. (Default)
01: Medium priority.
10: Highest priority.
11: Illegal.
Note:
ALPHA2_WIN_PRIORITY (Alpha Window 2 Priority). Determines the priority of Alpha Window 2. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha windows.
00: Lowest priority. (Default)
01: Medium priority.
10: Highest priority.
11: Illegal.
Note:
ALPHA1_WIN_PRIORITY (Alpha Window 1 Priority). Determines the priority of Alpha Window 1. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha windows.

clock beginning with the next VSYNC.
If SIGN_FREE (bit 2) = 1, the signature register captures the pixel data signature continuously across multiple frames.
If SIGN_FREE (bit 2) = 0, a signature is captured for one frame at a time, starting from the next falling VSYNC.
Priority of enabled alpha windows must be different.
Priority of enabled alpha windows must be different.
Priority of enabled alpha windows must be different.
