Register Descriptions

The FRT has the following registers.
• Free-running counter (FRC)
• Output compare register A (OCRA)
• Output compare register B (OCRB)
• Input capture register A (ICRA)
• Input capture register B (ICRB)
• Input capture register C (ICRC)
• Input capture register D (ICRD)
• Output compare register AR (OCRAR)
• Output compare register AF (OCRAF)
• Output compare register DM (OCRDM)
• Timer interrupt enable register (TIER)
• Timer control/status register (TCSR)
• Timer control register (TCR)
• Timer output compare control register (TOCR)
Note: OCRA and OCRB share the same address. Register selection is controlled by the OCRS
bit in TOCR. ICRA, ICRB, and ICRC share the same addresses with OCRAR, OCRAF,
and OCRDM. Register selection is controlled by the ICRS bit in TOCR.
