Feedback from a Swedish Customer on the Sunplus Controller Chip as used on the SP 5-GFX1.

"I noticed that 6.20.1 in manual 1.4 (1.3 Nov 07,2002) hold faulty information. Correct information is found in 6.25, command 20.

They both describe the same thing but bit4, bit5 and bit 6 differs. 

The data in Chapter 6.25 Table 13, command 20 is correct! This will make the page to blink. 

The data in 6.20.1 is faulty and will make the whole display to go black."
