8.3
8.3.1
The timer counters (TCNT) and general registers (TGR) are 16-bit registers. A 16-bit data bus to
the bus master enables 16-bit read/writes. 8-bit read/write is not possible. Always access in 16-bit
units. Figure 8.3 shows an example of 16-bit register access operation.
8.3.2
All registers other than the TCNT and general registers (TGR) are 8-bit registers. These are
connected to the CPU by a 16-bit data bus, so 16-bit read/writes and as 8-bit read/writes are both
possible (figures 8.3, 8.4, 8.5).

1. Minimum of two channel SYNC bits must be set to 1 for synchronous operation.
2. TCNT counter clear sources (CCLR2–CCLR0 bits of the TCR register) must be set in
