KXTF9 in IMU-3000EVB question

Hi, I am trying to use the IMU-3000 Eval board with a PIC32, I am able to communicate using I2c with the IMU without problems, I can get temp and gyro data but I can not talk to the Kionix acceleromenter. Please could someone tell me exactly the steps I need to initialize it and using it through the IMU-3000.

Thanks in advance

The kionix accel can be controlled using the IMU-3000 using the I2C Slave Interface registers.

The AUX Slave Address register (0x14), Aux VDDIO (0x13), Aux Slave Address (0x14), Aux Burst Read Address (0x18), and User Control Register, (0x3D), must be set appropriately to read data from the secondary accel.

Please review the register map document:
