29 / 98 page ![]() NXP Semiconductors FXLS8964AF 3-Axis Low-g Accelerometer Auto-increment Address Name Type Register Address F_READ = 0 F_READ = 1 Default Values BT_MODE = GND/[VDD] Comment BUF _Y_LSB[1][3][4] R 0Eh 0Fh 10h/0Ch/0Eh — Head/Tail sample of output buffer Y-axis LSB - buf_y_out[7:0] when SENS_CONFIG2[LE_BE] = 0 and buf_y_out[11:4] when SENS_CONFIG2[ LE_BE ] = 1. When SENS_CONFIG5[Y_DIS] = 1, this register is skipped over by the auto-increment mechanism. BUF _Y_MSB[1][3][4] R 0Fh 10h/0Ch/0Eh — Head/Tail sample of output buffer Y-axis MSB - buf_Y_out[11:8] when SENS_CONFIG2[LE_BE] = 0 and buf_y_out[3:0] when SENS_CONFIG2[LE_BE] = 1. When SENS_CONFIG5[Y_DIS] = 1, this register is skipped over by the auto-increment mechanism. BUF_Z_LSB[1][3][4] R 10h 11h 0Ch/0Eh/10h — Head/Tail sample of output buffer Z-axis LSB - buf_z_out[7:0] when SENS_CONFIG2[LE_BE] = 0 and buf_z_out[11:4] when SENS_CONFIG2[LE_BE] = 1. When SENS_CONFIG5[Z_DIS] = 1, this register is skipped over by the auto-increment mechanism. BUF_Z_MSB[1][3][4] R 11h 0Ch/0Eh/10h — Head/Tail sample of output buffer Z-axis MSB - buf_Z_out[11:8] when SENS_CONFIG2[LE_BE] = 0 and buf_z_out[3:0] when SENS_CONFIG2[LE_BE] = 1. When SENS_CONFIG5[Z_DIS] = 1, this register is skipped over by the auto-increment mechanism.
