Universal Serial Bus (USB)

This RSK device is fitted with a USB host socket (type A) and a function socket (type Mini B). USB module
USB0 is connected to the host and function socket, and can operate as either a host or function device. The
connections for the USB0 module are shown in Table 5-7 below.

Note:
•
When evaluating OTG, ensure to replace the default USB connector (USB0_3) with a USB Micro-AB
connector.
•
Connectors such as the one manufactured by Hirose Electric with part number ZX62R-AB-5P, can be
used.

5.10 I C Bus (Inter-IC Bus)
The RX111 features one I
(Electronically-Erasable Programmable Read Only Memory). Specific details of the EEPROM device and the
connections can be found in the board schematics.
The first bit of the device address can be configured by modifying option links – refer to §6 for further details.
