3.2 USB
This Bluetooth module contains a full speed (12Mbit/s) USB interface that is
capable of driving a USB cable directly. No external USB transceiver is required.
The device operates as a USB peripheral, responding to requests from a master
host controller such as a PC. Both the OHCI and the UHCI standards art
supported. The set of USB endpoints implemented can behave as specified in
the USB section of the Bluetooth specification v2.0 + EDR or alternatively can
appear as a set of endpoints appropriate to USB audio devices such as a set of
USB speakers.
USB is a master/slave oriented system (in common with other USB peripherals).
This Module only supports USB slave operation.
3.3 I²C
PIO[8:6] can be used to form an interface. The interface is driven by “bit
banging” these PIO pins using software. Therefore it is suited only to relatively
slow functions such as driving a dot matrix liquid crystal display (LCD).
Note. PIO[7:6] dual functions, UART bypass and EEPROM support, therefore
devices using an EEPROM connect support UART bypass mode. PIO Lines
need to be pulled-up through 2.2KΩ resisters.
