361 / 923 page  323 12.3.2 8-Bit Registers 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 12.4 ,12.5, and 12.6). TCR Bus interface Upper 8 bits Lower 8 bits Bus master Internal data bus Module data bus Figure 12.4 8-Bit Register Access Operation (Bus Master ↔ TCR (Upper 8 Bits)) TMDR Bus interface Upper 8 bits Lower 8 bits Bus master Internal data bus Module data bus Figure 12.5 8-Bit Register Access Operation (Bus Master ↔ TMDR (Lower 8 Bits)) TCR TMDR Bus interface Upper 8 bits Lower 8 bits Bus master Internal data bus Module data bus Figure 12.6 8-Bit Register Access Operation (Bus Master ↔ TCR, TMDR (16 Bit)) |
