When the SPI interface is chosen (P1), the accelerometer data (at least the Z-axis) reads slightly differently than when I2C is chosen. The Z-axis reading should be approx. 1g when the chip package top faces up, but reads approx 0.95g. Performing calibration seems to have little to no effect.

Update: This only affects 4-wire SPI. The WIP 3-wire code seems unaffected by this.
