Description

3/2014 Initial release of document

8/2014

Added the following sections:

• Mechanical and Electrical Specifications

• Digital Interfaces

• Modes of Operation

• Functionality

• Register Descriptions

• Printed Circuit Board Layout and Device Mounting

11/2014

• Figure 1, removed BYP

• Table 2, removed T = 25°C from Test conditions

• Table 6, removed "Sensitivity error due to linear acceleration removed Zero Rate Offset

error due to linear acceleration Added footnote to Zero-rate Offset, Post-Board Mount"

• Section 5.2, image, added Latch and ELE connection

• Section 6.4, removed "Reading F_STATUS clears the SRC_FIFO bit in the 0x0B:

INT_SOURCE_FLAG register."

• Table 27, F_EVENT field, added bullet: To clear this flag, both F_OVF and F_WMKF

flags must be cleared. See F_STATUS for details.

• Table 27, F_EVENT field, added bullet: To clear this field, the F_EVENT flag must be

cleared.

• Table 29, SRC_FIFO field, changed flag descriptions from

1: F_OVF or F_WMKF are set, provided the FIFO interrupt is enabled

(CTRL_REG2[INT_EN_FIFO=1])

0: Cleared by reading the register

to

1: When F_Event flag is set (F_OVF or F_WMKF are set), provided the FIFO interrupt

is enabled (CTRL_REG2[INT_EN_FIFO=1])

0: Cleared when F_Event Flag gets cleared (whenever both F_OVF and F_WMKF get

cleared)

• Table 29, SRC_RT field, changed bullets from

• Indicates that the rate threshold event flag triggered the interrupt

• Cleared by reading RT_SRC register

to

• Indicates that the rate threshold event flag(s) triggered the interrupt (when XRT or

YRT or ZRT(logical OR) event threshold flags go high)

• Cleared when XRT, YRT or ZRT event threshold flags are cleared.

• Section 6.11, added: "It also clears the RT_SRC flag in the 0x0B: INT_SOURCE_FLAG

register."

• Added Table 54, Rate sensitivity changes with FSR_DOUBLE setting

11/2014

• Removed last two features items

• Minor changes to table 2, Temperature Sensor Characteristics

• In Mechanical Characteristics table, changed typical parameters for Zero-rate Offset,

Zero-rate Offset, Post-board Mount and Integral nonlinearity and updated table

footnotes.
