11.3
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
