Bus mode: The interface bus mode is determined by BM[1:0] and
{DB15, DB13} by the following relationship:

Chip Select. Chip is selected when CS1=”H” and CS0 = “L”. When the
chip is not selected, D[15:0] will be high impedance.
RST
I
1
When RST=”L”, all control registers are re-initialized by their default
states.
An RC Filter has been included on-chip. There is no need for external
RC noise filter. When RST is not used, connect the pin to VDD.
CD
I
1
Select Control data or Display data for read/write operation. In S9, CD
pin is not used. Connect CD to VSS when not used.
”L”: Control data
”H”: Display data
ID0
I
1
Used for production control.
Connect ID0 to VDD for “H” or VSS for “L”.
The wiring status of ID0 is available with PID[1:0] of the Get Status
command.
ID1
I
1
Select input data set for 8-bit mode.
ID1=0 : 8-bit input data are D[0, 2, 4, 6, 8, 10, 12, 14]
ID1=1 : 8-bit input data are D[0:7]
The wiring status of ID1 is available with PID[1:0] of the Get Status
command. Other than 8-bit mode, connect ID1 to VDD for “H” or VSS for
“L”.
WR0

WR[1:0] controls the read/write operation of the host interface. See
section Host Interface for more detail.
In parallel mode, the meaning of WR[1:0] depends on whether the
interface is in the 6800 mode or the 8080 mode. In serial interface
modes, these two pins are not used, connect them to VSS.
