4.2 USB Interface
BSM-700 has a full-speed (12Mbps) USB interface for communicating with other compatible digital devices.
The USB interface on BSM-700 acts as a USB peripheral, responding to requests from a master host
controller.BSM-700 supports the Universal Serial Bus Specification, Revision v2.0 (USB v2.0 Specification)
4.3 Digital Audio Interface
The audio PCM interface on the BSM-700 supports:
On-chip routing to Kalimba DSP
Continuous transmission and reception of PCM encoded audio data over Bluetooth.
Processor overhead reduction through hardware support for continual transmission and reception of PCM
data.
A bidirectional digital audio interface that routes directly into the baseband layer of the firmware.
Hardware on BSM-700 for sending data to and from a SCO connection.
PCM interface master, generating PCM_SYNC and PCM_CLK.
PCM interface slave, accepting externally generated PCM_SYNC and PCM_CLK.
Various clock formats including:
Long Frame Sync
Short Frame Sync
GCI timing environments
13-bit or 16-bit linear, 8-bit μ-law or A-law companded sample formats.
Receives and transmits on any selection of 3 of the first 4 slots following PCM_SYNC.

5 Notes on operation
5.1 Power-on Sequence
We recommend that the power supplies are all powered at the same time.
5.2 IO State at Reset and Recommended Termination Handling
The RESET# pin is an active low reset. Assert the reset signal for a period >5ms to ensure a full reset. The RESET
# pin is pulled down internally until the power on, then the pull switches to a strong pull up.
