Bus mode: The interface bus mode is determined by BM[1:0] and D[7:6]
by the following relationship:
Chip Select. Chip is selected when CS1=”H” and CS0 = “L”. When the
chip is not selected, D[7:0] will be high impedance.
When RST=”L”, all control registers are re-initialized by their default states.
Since UC1682 has built-in Power-ON Reset and Software Reset
command, RST pin is not required for proper chip operation.
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 V
Select Control data or Display data for read/write operation. In S9 modes,
CD pin is not used. Connect CD to V
ID pin is for production control. The connection will affect the content of
D[7] when using Get Status command. Connect to V
“L”.
WR[1:0] controls the read/write operation of the host interface. See Host
Interface section for more detail.
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 them to V
Bi-directional bus for both serial and parallel host interfaces.
In serial modes, connect D[0] to SCK, D[3] to SDA,
Connect unused pins to V
