5.7 I2C Interface
The I2C interface is an alternate function on SIO pins, configurable by
The Two-wire interface can interface a bi-directional wired-OR bus with two lines (SCL, SDA) and has master
/slave topology. The interface is capable of clock stretching. Data rates of 100 kbps and 400 kbps are
supported.
An I2C interface allows multiple masters and slaves to communicate over a shared wired-OR type bus
consisting two lines which normally sit at VCC. The BL600 module can only be configured as an I2C master
with additional constraint that it be the only master on the bus. The SCL is the clock line which is always
sourced by the master and SDA is a bi-directional data line which can be driven by any device on the bus.
IMPORTANT:
pull-up resistors on both SCL and SDA lines are not provided in the module and MUST be
provided external to the module.

The 28 SIO pins are configurable by
user configured features:
Input/output direction
Output drive strength (standard drive 0.5mA or high drive 5mA)
Note:
The
smart
BASIC firmware does support high drive since v1.5.65.0 (Feb. 2014).
Internal pull up and pull down resistors (13K typical) or no pull-up/down
Wake-up from high or low level triggers on all pins

This interface is an alternate function configurable by
smart BASIC. Default in the FW pin 14 and 16 are inputs.
I
SPIOPEN() in smart BASIC selects SPI function and changes pin14
