2.1 I

C module

The STMPE1600 is interfaced to the main processor using an I

C bus.

2.1.1 I

C address

The addressing scheme of STMPE1600 is designed to allow up to 8 devices to be

connected to the same I

C bus. The slave device address is a 7-bit or 10-bit address where

they are 42h, 43h, 44h, 45h, 46h, 47h, 48h and 49h (equivalent values in 7-bit and 10-bit

addressing).
