The same logic applies to On Gate Array, even if the duration of the CRTC VSYNCis reduced to 2 µseconds, the Gate Array will always output black for 26 lines with 4 lines instead of chars. The Gate Array C-VSYNC is considered complete when to the 26th line has been processedmonitor. Then While on ASIC/Pre-ASIC, the Gate Array stops outputting CRTC VSYNC must be active for the palette colour blackC-VSYNC signal to be sent by the ASIC to the monitor.

* H06 which counts the number of CRTC characters processed during an HSYNC. H06 is incremented by the Gate Array for each CRTC character when CRTC HSYNC is active. The Gate Array activates the C-HSYNC signal when H06 reaches 2, and changes its graphics mode if a change was pending. It deactivates this signal when H06 reaches 6.* V26 which counts the number of HSYNCs occuring during a VSYNC. V26 is incremented by the Gate Array when the CRTC signals an end of HSYNC. The Gate Array activates the C-VSYNC signal when V26 reaches 2. It deactivates this signal when V26 reaches 6. After the 26th line has been processed, the Gate Array stops outputting the palette colour black.
