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.
Figure 9.5 shows an example in which TCF is read when it contains H'AAFF.
