EVAL-ADXL345Z-DB LEDs connection

A customer bringing up a question on LEDs connection at EVAL-ADXL345Z-DB which he bought, seems different from schematic which is placed on UG-065 Evaluation Board User Guide, Rev.A.

We have also checked the actual board using digital multi meter, and awared LED1 is seemed connected to pin11 of J1, and also pin13 of UC1 of MCU. LED2 is also connected to pin18 of J2, as well as pin54 of UC1.  Subject to Figure 5. ADXL345 Development Board Schematic, of UG-065, LED1 is to pin54 and LED2 is to pin53 of UC1.

Here, in regard to these LED connection, the connection scheme of the actual board looks rather close to the schematic of EVAL-ADXL346Z-DB which is placed on same UG-065, than the schematic of ADXL345 in conjunction with it.


Please could you check and confirm above, and in case the schematic on UG-065 is wrong, please give us correct one. 

Or else, any comment to above would be very much appreciated.


Thank you very much for your support, and Best regards,
