5	R/W	H/L	Read/Write (R/W) signal for the 68-type microcontroller, or WRITE(WR) signal for the 80-type microcontroller. If a 68-type microcotroller is selected as the host microcontroller, this pin should be connected to the R/W output of the microcontroller. A HIGH level on this pin indicates that the microcontroller intends to read from the RW1020_X series. A LOW level on this pin indicates that the microcontroller intends to write to the RW1020_X series. If a 80-type microcontroller is selected as the host microcontroller, this pin should be connected to the WR output of the microcontroller. A LOW level on this pin indicates that the microcontroller intends to write to the RW1020_X series.
6	CS1	H/L	Enable signal (E) for the 68-type microcontroller, or READ (RD) signal for the 80-type microcontroller. If a 68-type microcotroller is selected as the host microcontroller, this pin should be connected to the ENABLE output of the microcontroller. A HIGH level on this pin indicates that the microcontroller intends to select the RW1020_X series. If a 80-type microcontroller is selected as the host microcontroller, this pin should be connected to the RD output of the microcontroller. A LOW level on this pin indicates that the microcontroller intends to read from the RW1020_X series..
7	DB0	H/L	Bi-direction, tri-state 8-bit parallel data bus for interface with a host microcontroller. This data bus is for data transfer between the host microcontroller and the RW1020_X.
8	DB1	H/L	Bi-direction, tri-state 8-bit parallel data bus for interface with a host microcontroller.

15	VEE	-	Negative Voltage Output
16	RES	H/L	Hardware RESET and interface type selection. This pin is a dual function pin. It can be used to reset the RW1020_X and select the type of interface timing. The hardware RESET is edge-sensitive. It is not level-sensitive. That is, either a falling edge or a rising edge on this pin can reset the chip. The voltage level after the reset pulse selects the type of interface timing. If the voltage level after the reset pulse stays at HIGH, interface timing for the 68-type microcontroller is selected. If the voltage level after the reset pulse stays at LOW, then interface timing for the 80-type microcontroller is selected. Therefore, a positive RESET pulse selects the 80-type microcontroller for interface and a negative RESET pulse selects the 68-type microcontroller for interface. The following diagram illustrates the reset pulse and the selected type of microcontroller.
