Pin Function Grouping
Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, VDD, gnd_1 gnd_2 etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

ADXL345BCCZ
Accelerometer X, Y, Z Axis ±2g, 4g, 8g, 16g 0.05Hz ~ 1.6kHz 14-LGA (3x5)
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer
with high resolution (13-bit) measurement at up to ±16 g. Digital
output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.
The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as
well as dynamic acceleration resulting from motion or shock. Its
high resolution (3.9 mg/LSB) enables measurement of inclination
changes less than 1.0°.
Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing
the acceleration on any axis with user-set thresholds. Tap sensing
detects single and double taps in any direction. Free-fall sensing
detects if the device is falling. These functions can be mapped
individually to either of two interrupt output pins. An integrated
memory management system with a 32-level first in, first out (FIFO)
buffer can be used to store data to minimize host processor activity
and lower overall system power consumption.
Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement
at extremely low power dissipation.
The ADXL345 is supplied in a small, thin, 3 mm × 5 mm × 1 mm,
14-lead, plastic package.
► Ultralow power: as low as 23 µA in measurement mode and
0.1 µA in standby mode at VS = 2.5 V (typical)
► Power consumption scales automatically with bandwidth
► User-selectable resolution
► Fixed 10-bit resolution
► Full resolution, where resolution increases with g range, up to
13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor
in all g ranges)
► Embedded memory management system with FIFO technology
minimizes host processor load
► Single tap/double tap detection
► Activity/inactivity monitoring
► Free-fall detection
► Supply voltage range: 2.0 V to 3.6 V
► I/O voltage range: 1.7 V to VS
► SPI (3- and 4-wire) and I2C digital interfaces
► Flexible interrupt modes mappable to either interrupt pin
► Measurement ranges selectable via serial command
► Bandwidth selectable via serial command
► Wide temperature range (−40°C to +85°C)
► 10,000 g shock survival
► Pb free/RoHS compliant
