65 / 100 page  NXP Semiconductors FXLS8971CF 3-Axis Low-g Accelerometer Bit 7 6 5 4 3 2 1 0 Name ORIENT_DBCOUNT[7:0] Reset 0 0 0 0 0 0 0 0 Access R/W R/W R/W R/W R/W R/W R/W R/W Table 86. ORIENT_DBCOUNT register (address 2Ah) bit allocation Field Description 7 to 0 ORIENT_ DBCOUNT[7:0] 8-bit unsigned orientation debounce counter value A new orientation must be maintained for the minimum number of ODR periods specified in order for the orientation to be considered valid before asserting the ORIENT_STATUS[NEW_ ORIENT ] event flag. ORIENT_CONFIG[ORIENT_DBCNTM] controls the counter behavior. The selected ODR in LPM and HPM modes and the effective ODR when operating in FPM determines the debounce counter period. Calculate the minimum debounce latency time by: Debounce_time = (ODR–1 * ORIENT_DBCOUNT) Note: If the applied acceleration is greater than 1.25 g on any axis, the debounce counter is held at the current value (frozen).
