LEDs

The LEDs on the MCB2103 board are:

• The POWER LED indicates that power is present on the board.
• P0.16 - P0.23 connect to eight Port 0 pins when jumper J6 is installed. These LEDs can display program status while testing your applications. Removing Jumper J6 disables the LED drivers.

Note

• Early device variants may not have pull-up resistors on P0.17 and P0.18. As a result, these LEDs may not be active.
