11.7 Window Write Register Programming
Window data read/write is supported in the AL440B to benefit the designing effort for applications
such as PIP display. The window mode is enabled by driving low on /SDAEN signal. A serial bus
can program built-in registers to set up coordinates of the window and the settings take effect
following by next read/write reset pulse. Window mirroring can cooperate with the window mode
data access to flip window data in x or y direction. When window-mirroring function is turned on,
write data can be stored in reverse sequence.
The serial communication interface consists of 3 signals, they are SCL (serial clock), SDA (serial
data) and /SDAEN (window mode enable). The serial communication interface is enabled by driving
low on /SDAEN signal. The detail operation timing of the serial bus is illustrated in chapter 10. In
Window read/write mode, read and/or write may begin at the start address of any of the 8192 blocks.
Each block is 64 bytes in length. (8192 blocks x 64 byte = 512 kbytes)
