pinout and notes about them. Jumpers functions are described. Notes and info on specific

peripherals are presented. Notes regarding the interfaces are given.

5.1 Communication with MOD-IO

There are several ways for communication with MOD-IO and its main microcontroller

ATMEGA16A.

The three typical communication routines are: via I2C by utilizing the default firmware; via ISP

with a compatible programmer tool and writing own code; via JTAG with a compatible debugger

tool and writing own code.

The communication with the board's default firmware is performed typically via the I2C line that

might be found on the UEXT connector. For more information on how the default firmware might

be accessed please refer to chapter 2.6.
