13.3.2 Read access
In order to read data from the sensor, the following procedure must be done:

output enable and slave output enable just symbolize if the master or the slave output is
enabled or disabled respectively.

Start condition: The master drives a rising edge after a LOW level
Command: The master sends a read command, that is the last bit is set
Handover: The master sends a handover bit, that is a logic 0 and disables his output
after a three-quarter bit period
Takeover: The slave drives a LOW level after the falling edge for t
Data: The slave sends two data bytes
Handover: The slave sends a handover bit, that is a logic 0 and disables his output
after a three-quarter bit period
Takeover: The master drives a LOW level after the falling edge for t
Stop condition: The master drives a rising edge after a LOW level

(1) Duration of LOW level for slave takeover t
(2) There is an overlap in the output enables of master and slave, because both drive a LOW level.
(3) Duration of LOW level for master takeover t
(4) If the master does not take the bus and a pull-up exists, the stop condition is generated by the
(5) If the master might not drive the bus, the bus is defined by the bus-pull.
However this ensures the independency from having a pull-up or pull-down on the bus. In
addition it improves the ElectroMagnetic Compatibility (EMC) robustness, because all levels
are actively driven.
