Hardware Connection
The hardware connection of SC16IS752/762 in Figure 1 shows the jumpers setting on the
SC16IS752/762 demo board and how to connect the demo board to the computers with RS-232
cables. The steps how to connect them are described as follows
1. Use a RS-232 Cable such as a 9-pin null modem cable to connect the 9-pin connector on P1
2. Place a jumper to pin 1 and pin 2 on JP2 to select the I2C-bus interface between the host
3. Set the I2C device address of SC16IS752/762 Bridge IC to 0x9A by shorting pin A0 to VSS
4. Set the JP16 jumper to the hard reset to allow the S1 push button to reset both the LPC935
5. Remove the jumper on JP20
6. Place a jumper to pin 1 and pin 2 on JP8 for the serial loop back communication. The LED
7. Place a jumper on JP17 to use either the external power plugged into the DC power jack on
