Section 9 Timers
Write Access: Write access to the upper byte results in transfer of the upper-byte write data to
TEMP. Next, write access to the lower byte results in transfer of the data in TEMP to the upper
register byte, and direct transfer of the lower-byte write data to the lower register byte.
Figure 9.18 shows an example of the writing of H'AA55 to FRC.
