Section 10 Advanced Timer Unit (ATU)
10.5.2
Free-running counters 1 to 9 (TCNT1 to TCNT9), the general registers (GR), down-counters
(DCNT), offset base register (OSBR), cycle registers (CYLR), buffer registers (BFR), duty
registers (DTR), and timer start register (TSTR) are 16-bit registers. These registers are connected
to the CPU via an internal 16-bit data bus, and can be read or written (read only, in the case of
OSBR) a word at a time.
Figure 10.39 shows the operation when performing a word read or write access to TCNT1.
