12.3 Register Descriptions
The TMR has the following registers. For details on the serial timer control register, refer to
section 3.2.3, Serial Timer Control Register (STCR). For details on timer connection register S,
refer to section 13.3.3, Timer Connection Register S (TCONRS).
• Timer counter (TCNT)
• Time constant register A (TCORA)
• Time constant register B (TCORB)
• Timer control register (TCR)
• Timer control/status register (TCSR)
• Timer input select register (TISR)*¹
• Time constant register C (TCORC)*²
• Input capture register R (TICRR)*²
• Input capture register F (TICRF)*²
Notes: 1. TISR is only for the TMR_Y.
2. TCORC, TICRR, and TICRF are only for the TMR_X.
