3.2 Power supply and LED indicators
In the ISP1362 OTG add-on evaluation card, the power supply inputs, +3.3 V and +5.0 V,
come from the IDP. Therefore, no other external power supply input or on-board power
regulation is required.
There are LEDs on the board to indicate the power supply status:
• D1 is the +3.3 V indicator.
• D2 is the +5.0 V indicator.
• D3 is the GoodLink1 indicator for the device controller.
3.3 Connectors and jumpers
The ISP1362 OTG add-on card contains an OTG connector (J2) and a USB downstream
port connector (J1) to interface with other USB peripherals. Jumper JP1 sets the OTG
port to OTG or non-OTG mode, while JP2 disables the host port.
There is also a reset switch (S1) for the hardware reset of the ISP1362.
Table 1 shows the jumper settings that must be configured before using the ISP1362
OTG add-on card.
