Rev: b Low power Multimedia Bluetooth™ Module with antenna F2M03MLA Datasheet 6.2.10 IEC 60958 Interface The IEC 60958 interface is a digital audio interface that uses bi-phase coding to minimise the DC content of the transmitted signal and allows the receiver to decode the clock information from the transmitted signal. The IEC 60958 specification is based on the two industry standards AES/EBU and the Sony and Philips interface specification SPDIF.

Rev: b Low power Multimedia Bluetooth™ Module with antenna F2M03MLA Datasheet 6.2.12 Microphone Input The audio-input is intended for use from 1µV@94dB SPL to about 10µV@94dB SPL. With biasing-resistors R1 and R2 equal to 1kΩ, this requires microphones with sensitivity between about –40dBV/Pa and -60dBV/Pa. The microphone for each channel should be biased as shown in the figure below.
PAGE 30
Rev: b Low power Multimedia Bluetooth™ Module with antenna F2M03MLA Datasheet 6.2.14 Output Stage The output digital circuitry converts the signal from 16-bit per sample, linear PCM of variable sampling frequency to an 8 MBits/sec bit stream, which is fed into the analogue output circuitry. The output circuit comprises a digital to analogue converter with gain setting and output amplifier.

Rev: b Low power Multimedia Bluetooth™ Module with antenna F2M03MLA Datasheet 6.3 UART Interface The F2M03MLA Bluetooth module’s Universal Asynchronous Receiver Transmitter (UART) interface provides a simple mechanism for communicating with other serial devices using the RS232 standard(1). Universal Asynchronous Receiver Four signals are used to implement the UART function, as shown in the figure above.
PAGE 32
Rev: b Low power Multimedia Bluetooth™ Module with antenna F2M03MLA Datasheet The UART interface is capable of resetting the Free2move module upon reception of a break signal. A Break is identified by a continuous logic low on the UART_RX terminal, as shown in figure below. If tBRK is longer than a special value, defined by the Free2move firmware a reset will occur. This feature allows a host to initialise the system to a known state.

Rev: b Low power Multimedia Bluetooth™ Module with antenna F2M03MLA Datasheet 6.4 Serial Peripheral Interface F2M03MLA is a slave device that uses terminals SPI_MOSI, SPI_MISO, SPI_CLK and SPI_CSB. This interface is used for program emulation/debug and IC test. It is also the means by which the F2M03MLA flash may be programmed, before any 'boot' program is loaded.
