Use for configuration purpose.
CS0/A0
CS1/A1
I
Chip Select or Chip Address. In parallel mode and S8 mode, chip is
selected when CS0=”L” and CS1=”H”.
In I
2
C mode, A[1:0] specifies bit 3~2 of UC1602I’s device address.
When the chip is not selected, D[7:0] will be high impedance.
RST
I
When RST=”L”, all control registers are re-initialized by their default
states and/or by their pin configurations if applicable.
When RST is not used, connect the pin to V
DD1
.
CD
I
Select Control data or Display data for read/write operation. CD pin is
not used in I
C modes, connect it to V
DD
or V
SS.
”L”: Control data
”H”: Display data
WR0
WR1
I
WR[1:0] controls the read/write operation of the host interface.
In parallel mode, WR[1:0] meaning 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 to V
SS
.
D0~D7
I/O
Bi-directional bus for both serial and parallel host interfaces.
In S8 mode, connect unused pins to V
DD
or V
SS
. In I2C mode, connect
D[1:0] to SCK, and D[5:2] to SDA, and D[7:6] to V
DD
or V
SS
.
In I
2
C mode, SDA and SCK are in open-drain mode. Pull up resistors are
required on the bus. In COG applications, be careful to control ITO trace
resistance, as it will affect effective output level of SDA.
