me: "Bits 5-4 indicate the video mode", how do you derive VIDEO_MASK_00b = 0x03C0 from this?

Granite 4.1 8B: "I apologize for the confusion earlier. Let's clarify the derivation of the VIDEO__MASK_00b based on the description "Bits 5-6 indicate the video mode" from the equipment_list section.

Given that bits 5 and 6 are used for video mode, we need to create a mask that isolates these two bits:

Bit 5 is the least significant bit of the group (2^5 = 32 decimal, 0b00100000 in 8-bit form). Bit 6 is the next bit up (2^6 = 64 decimal, 0b01000000 in 8-bit form). Combining these bits: ...

Therefore, the correct mask for VIDEO_MASK_00b should be 0x00C0"

Errors on top of errors when converting description into binary numbers. Its hopeless for basic task like parsing/generating headers :(
