7.3. SPI Interface
The application controller interface (ACI) uses a standard SPI slave interface as the transport
Layer on five physical wires:
2 control wires (clock and slave select)
2 data wires with serial shift-out (MOSI and MISO) in full duplex
1 wire to indicate data availability from the slave
All the SPI pins have an internal pull-down except for the SPI_CS that has a pull-up. All the SPI
pins, except the SPI_CS, are in high impedance state during the low-power states. The SPI_IRQ pin
requires an external pull-down resistor.

7.4. Clocks
The BMD-100 integrates two low-speed frequency oscillators (LSOSC) and two high-speed
(32 MHz) frequency oscillators (HSOSC).
