CC2530: 2.4 GHz wireless MCU

Hi,

It seems I2C is available in CC2533 and CC2541 only.

On the CC2533 and CC2541, the I2C module is connected to pins 2 and 3 and uses the P2 interrupt to the

CPU. Pins 2 and 3 can alternatively be controlled as two GPIO pins if they are not used by the I2C module.

Please refer to section - I2C of CC253x User Guide (SWRU191) for further details.

2-Wire debug is available in CC253x devices.

The two-wire debug interface allows programming of the on-chip flash, and it provides access to memory

and register contents and debug features such as breakpoints, single-stepping, and register modification.

The debug interface uses I/O pins P2.1 and P2.2 as debug data and debug clock, respectively, during

debug mode. These I/O pins can be used as general-purpose I/O only while the device is not in debug

mode. Thus, the debug interface does not interfere with any peripheral I/O pins.

Please refer to section - Debug Interface of CC253x User Guide (SWRU191) for further details.

Thanks,

PM
