(At the time of reset: {SBA7, SBA6, SBA5, SBA4} = 9H, read address: 3H)

Set bottom address of scroll data area in RAM. 0 <= Scroll bottom address <= 67 ;

Scroll top address must < Scroll bottom address

8.2.28 Scroll Specified Address

(At the time of reset: {SSA3, SSA2, SSA1, SSA0} = FH, read address: 4H)

(At the time of reset: {SSA7, SSA6, SSA5, SSA4} = 9H, read address: 5H)

According to the display panel size or the duty ratio selection, set the specified address

in RAM where to jump to the scroll bottom address and then show the fixed data area.

Scroll specified address = scroll top address + panel scroll area – 1

8.2.29 Scroll Start Address

(At the time of reset: {SAY3, SAY2, SAY1, SAY0} = 0H, read address: 6H)

(At the time of reset: {SAY7, SAY6, SAY5, SAY4} = 0H, read address: 7H)

Set the starting address of the area scrolling and then executes the area scroll

operation. The scroll start address must be in the scrolling area.

Scroll top address <= Scroll start address <= Scroll bottom address

Note: The setting sequence of Scroll start address registers must be setting SAY[7:4]

(Bank 3[7H]) first, then setting SAY[3:0] (Bank 3[6H]), to prevent error.

– mark means “Don’t care”
