TCNT and TGR are 16-bit registers. As the data bus to the bus master is 16 bits wide, these registers can be read and
written to in 16-bit units.
These registers cannot be read or written to in 8-bit units; 16-bit access must always be used.
An example of 16-bit register access operation is shown in figure 10-2.
