7.4 USB Interface
A USB device interface compliant to USB specification v1.1 is connected to the ARM processor. This al-
lows the chip to be connected to a Universal Serial Bus that can transmit data and/or voice through the
internal USB transceiver.
Figure 5 gives an overview of the main components needed for supporting the USB interface, as specified
in the Bluetooth
port Layer) is also shown.
Figure 5. USB Interface
The USB device registers and FIFOs are memory mapped. The USB Driver will use these registers to ac-
cess the USB interface. The equivalent exists for the HCI communication over UART.
For transmission to the host, the USB & Serial Drivers interface with the HW via a set of registers and
FIFOs, while in the other direction, the hardware may trigger the Drivers through a set of interrupts (iden-
tified by the RTOS, and directed to the appropriate Driver routines).
7.5 JTAG Interface
The JTAG interface is compliant with the JTAG IEEE Std 1149.1. Its allows both the boundary scan of the
digital pins and the debug of the ARM7TDMI application when connected with the standard ARM7 devel-
opment tools.
7.6 RF Interface
The STLC2415 radio interface is compatible to BlueRF (unidirectional RxMode2 for data and unidirection-
al serial interface for control).
7.7 PCM Voice Interface
The PCM interface is a direct PCM interface to connect to a standard CODEC (e.g. STw5093 or STw5094)
