Value

R/W

VSYNC

Vertical scanning synchronization pulse period

Vertical scanning display period

Note: In positive mode the synchronization period takes place

when VSYNC equals logic 1.

HSYNC

Horizontal scanning synchronization pulse period

Horizontal scanning display period

Note: In positive mode the synchronization period takes place

when HSYNC equals logic 1.

15:5



Wired to zero.

LSB

Outputs 0 on LSB of R/G in pixel mode

Outputs 1 on LSB of R/G in pixel mode

R/W

MODE

Dot mode: Outputs dots and dot clock

Pixel mode: Outputs pixels serially and pixel clock

R/W

NSYNC

Normal mode: Outputs sync signals low active

Positive mode: Outputs sync signals high active

R/W

CSEL

Outputs VSYNC signal from VSYNC pin

Outputs CSYNC signal from VSYNC pin

R/W

ESYNC

Sets HSYNC and VSYNC pins to output mode

Sets HSYNC and VSYNC pins to input mode

R/W

Note:

When outputting a digital RGB signal, you must set bits [15:0] of PAMUX register in module

PORT to 1.

Start Address Register A/E, B, C, D (SARA/E, SARB, SARC, SARD)

Segment Address

These bits specify the segment start address of each layer’s frame

buffer.

R/W

Address Counter

These bits specify the start address within the segment defined by

SA of each layer’s frame buffer.

R/W

Dot Position

These bits specify the first visible dot within the first word addressed

by AC. Note that SS width differs for layer A/B and C/D and does

not matter for layer E. The SS[2] bit is not relevant for layers A and
