256 / 508 page ![]() Section 9 Timers Rev. 1.00 May 30, 2008 Page 236 of 484 REJ09B0436-0100 Figure 9.4 shows an example in which H'AA55 is written to TCF. Write to upper byte CPU (H'AA) TEMP (H'AA) TCFH ( ) TCFL ( ) Bus interface Module data bus Write to lower byte CPU (H'55) TEMP (H'AA) TCFH (H'AA) TCFL (H'55) Bus interface Module data bus Figure 9.4 Write Access to TCR (CPU → TCF) (2) Read Access In access to TCF, when the upper byte is read the upper-byte data is transferred directly to the CPU and the lower-byte data is transferred to TEMP. Next, when the lower byte is read, the lower- byte data in TEMP is transferred to the CPU. In access to OCRF, when the upper byte is read the upper-byte data is transferred directly to the CPU. When the lower byte is read, the lower-byte data is transferred directly to the CPU. |
