Notes: 1. Lower 16 bits of the address.

2. Bits 7 to 1 are read-only; only 0 can be written to clear the flags.

Bit 0 is readable/writable.

3. OCRA and OCRB share the same address. Access is controlled by the OCRS

bit in TOCR.

4. ICRA, ICRB, and ICRC share the same addresses with OCRAR, OCRAF, and

OCRDM. Access is controlled by the ICRS bit in TOCR.
