NOTES:1 An external pull-up is required on the LOWPOWER pin for proper functionality. The external pull-up is not shown in the evaluation board schematics, but has been added on the evaluation board. 2 An external pull-up is required on any GPIO pins that is used as an input. In the suspend mode, the internal pull-up resistor is disabled and the input will be floating if there is no external pull-up resistor. The external pull-ups have not been added to the GPIOs used as inputs on this evaluation board.

Jumper Settings Common jumpers

Common jumpers are those jumpers which should be set the same for both RS-232 and RS-485 mode. The Table 2 shows the common jumpers setting on the evaluation board:
