Command setting

D[7:0]

SDA

SMX, SMY, SRGB

-If those register not change, those H/W pins are always valid. If those registers be changed, should be follow

registers setting.

-When Power On or H/W reset, those function follow H/W pins setting first.

Function

-By command setting

Normal /

Partial mode

-By command setting

-By Command setting

Idle Mode

(IDM H/W pin)

-By IDM H/W pin

-IDM On/OFF (39h/28h) are disable

Display On/ Off

(SHUT H/W pin)

-By SHUT H/W pin

-SLPIN(10h), SLPOUT(11h), Display

On/OFF (29h/28h) are disable

Data inverter setting

(REV H/W pin)

-By command setting

-Don’t care in this mode, but should be set to VDDI or DGND

-By REV H/W pin

-INVON/OFF (21h/20h) are disable

DE H/W pin

-The data latched by rising edge of

PCLK when DE=’1’

-When display data coming the DE

signal should be VDDI level

-When DE='0' area, the data of GRAM

will keep the same status.

RL H/W pin

TB H/W pin

-Don’t care in this mode, but should be

set to VDDI or DGND

-Don’t care in this mode, but should

be set to VDDI or DGND

-By H/W pin

-No commands conflict

Blanking porch

-Don’t care in this mode

-Control by DE signal

-Control by RGBBPCTR (B5h)

Colors format

-Control by IFPF[2:0] of COLMOD(3A)

-Control by VIPF[3:0] of COLMOD(3A)

Note 1: RCM1 and RCM0 are H/W setting pins.

Note 2: In RGB + SPI I/F (RCM="1x"), VS, HS, DE, PCLK and D[17:0] are Hi-Z by Driver and can be stop for Host, when

ICM='1'.

Note 3: In RGB + SPI I/F (RCM="1x"), the data deliver via GRAM

Note 4: When Power on Driver IC should be detect SMX, SMY, SRGB H/W setting

Note 5: When Power on Driver IC should be detect RCM1, RCM0 H/W setting and get into the I/F mode.

Note 6: When Power on Driver IC should be detect LCM1, LCM0 H/W setting and get into the setting mode.
