The Rev B data sheet states that for register 0x2D, bit 0 that: Standby mode. In standby mode, the device is in a low power state, and the temperature and acceleration data paths are not operating. In addition, digital functions, including FIFO pointers, reset. Changes to the configuration setting of the device must be made when standby = 1. An exception is a high-pass filter that can be changed when the device is operating. Elsewhere it states that other settings, like self-test and reset registers can be changed. The data sheet is ambiguous when it comes to WHICH registers are locked in measurement mode.
The data sheet does not clearly define which registers are considered "configuration" registers that enter the locked state when in the measurement mode. In particular, are the Range settings [0:1] in register 0x2C locked when in in the measurement mode?
Consider adding a column to Table 15 to define which registers are locked in Measurement mode. This would also help highlight this function and the potential issues it might create if the written notes are missed.
