Technical Note
5) Built-in HOST CPU interface
For 8-bit/16-bit bus interface in parallel interface.
Read/ write access to frame memory.
Read/ write access to internal registers (Indirect access with a index register as the address).
Read/ write access to the LCD controller: Parallel/Serial (Direct access available via the LCD interface).
6) Extended overlay function
Supporting overlay of icon-data/font-data of up to two points during LCD data transfer.
Both icon-data and font-data corresponding to 65536 display colors. Possible to setting transparent colors.
7) LED interface, GIO function
Built-in PWM output of 4 systems for 3 color LED controls and white LED control.
7 GIO's in total available for the GIO function.
8) Clock generation, power management function
Oscillation circuit configuration by XIN and XOUT terminals, or clock input from XIN terminal available.
Built-in PLL in BU6568GV.
Clock control of IC inside in unit of block (suspend mode available).
9) Key interfaces built in
3 systems of key interfaces built in. Interruption to be generated at key input.
Useable for removing software chattering.
＊Data is prepared separately about each register setup. Please refer to the Development Scheme on page 14.
