With CS tied high to V
requiring a simple 2-wire connection as shown in
The ADXL312 conforms to the UM10204 I
and User Manual, Rev. 03—19 June 2007, available from NXP
Semiconductor. It supports standard (100 kHz) and fast (400 kHz)
data transfer modes if the bus parameters given in
Table 11

alternate I
chosen by grounding the ALT ADDRESS pin (Pin 7). This
translates to 0xA6 for a write and 0xA7 for a read.
