FRC, OCRA, OCRB, and ICRA to ICRD are 16-bit registers, but the CPU is connected to the on-
chip peripheral modules by an 8-bit data bus. When the CPU accesses these registers, it therefore
uses an 8-bit temporary register (TEMP).
These registers should always be accessed 16 bits at a time. If two consecutive byte-size MOV
instructions are used, the upper byte must be accessed first and the lower byte second. Data will
not be transferred correctly if only the upper byte or only the lower byte is accessed.
