Self-contained Run Mode
Selected by nAutoRUN pin status:
LOW (0V). Then runs $autorun$ ( smart BASIC
application) if it exists.
Interactive Development

Note 1:
1:1:
1: DSR, DTR, RI, and DCD can be implemented in the smart BASIC application.

2: With I2C interface selected, pull-up resistors on I2C SDA and I2C SCL MUST be connected
externally as per I2C standard.

::
: SPI interface consists of SPI MOSI, SPI MISO and SPI CLK. SPI CS is created by customer using any
spare SIO pin within their smart BASIC application script allowing multi-dropping.

NoteNote
Note 4:
4:4:
4: BT900 module comes loaded with smart BASIC runtime engine FW, but does not come loaded
with any smart BASIC application script (as that is dependent on customer end application or use).
Laird provides many sample smart BASIC applications covering the services listed.

::
: Deep sleep consumes 233uA of power when the BT900 internal radio chip 32.768kHz is used. The
smart BASIC runtime engine firmware (v9.1.2.0) has SIO (DIO default function) input pins that are
PULL-UP enabled by default. You may disable the internal PULL_UP through a smart BASIC
