Section 10 16-Bit Timer Pulse Unit (TPU)
10.4
10.4.1
TCNT and TGR are 16-bit registers. As the data bus to the master is 16 bits wide, these registers
can 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 10.3.
10.4.2
Registers other than TCNT and TGR are 8-bit. As the data bus to the CPU is 16 bits wide, these
registers can be read and written to in 16-bit units. They can also be read and written to in 8-bit
units.
Examples of 8-bit register access operation are shown in figure 10.4, 10.5, and 10.6.
