132-RGB X 176-DOT 1-CHIP DRIVER IC FOR 262,144-COLOR TFT-LCD DISPLAY
WINDOW ADDRESS FUNCTION
Preliminary
When data is written to the on-chip GRAM, a window address-range which is specified by the horizontal address
register (start: HSA7-0, end: HEA 7-0) and vertical address register (start: VSA7-0, end: VEA7-0) can be updated
consecutively.
Data is written to addresses in the direction specified by the AM and ID1-0bit. When image data, etc. is being written,
data can be written consecutively without thinking a data wrap by doing this.
The window must be specified to be within the GRAM address area described as following example. Addresses
must be set within the window address.
[Restriction on window address-range settings]
(horizontal direction) 00H ≤ HSA7-0 ≤ HEA7-0 ≤ 83H
(vertical direction) 00H ≤ VSA7-0 ≤ VEA7-0 ≤ AFH
[Restriction on address settings during the window address]
(RAM address) HSA7-0 ≤ AD7-0 ≤ HEA7-0
VSA7-0 ≤ AD15-8 ≤ VEA7-0
Note: In high-speed RAM-write mode, the lower two bits of the address must be set as shown below according to the
value of the ID0 bit.
ID0=0: The lower two bits of the address must be set to 11.
ID0=1: The lower two bits of the address must be set to 00.
