Read Access: When the upper byte of TCF is read, the upper-byte data is sent directly to the CPU,
and the lower byte is loaded into TEMP. Next when the lower byte is read, the lower byte in
TEMP is sent to the CPU.
When the upper byte of OCRF is read, the upper-byte data is sent directly to the CPU. Next when
the lower byte is read, the lower-byte data is sent directly to the CPU.
