MPU Parallel interface bus and serial interface select
If use RGB Interface must select serial interface.
* : Fix this pin at VDDI or VSS.
This signal will reset the device and must be applied to properly
initialize the chip.
Signal is active low.
Extended command set enable.
Low: extended command set is discarded.
High: extended command set is accepted.
Please connect EXTC to VDDI to read/write extended registers
(RB0h~RCFh, RE0h~RFFh)
Chip select input pin (“Low” enable).
This pin can be permanently fixed “Low” in MPU interface mode only.
* note1,2
This pin is used to select “Data or Command” in the parallel interface
or 4-wire 8-bit serial data interface.
When DCX = ’1’, data is selected.
When DCX = ’0’, command is selected.
This pin is used serial interface clock in 3-wire 9-bit / 4-wire 8-bit
serial data interface.
If not used, this pin should be connected to VDDI or VSS.
