Input Capture Register (TICR) [TMRX Additional Function]

—

Bit

Initial value

Read/Write

TICR is an 8-bit internal register to which the contents of TCNT are transferred on the falling edge

of external reset input. The CPU cannot read or write to TICR directly.

The TICR function is used in timer connection. For details, see section 13, Timer Connection.

12.2.10

Time Constant Register C (TCORC) [TMRX Additional Function]

R/W

Bit

Initial value

Read/Write

TCORC is an 8-bit readable/writable register. The sum of the contents of TCORC and TICR is

continually compared with the value in TCNT. When a match is detected, a compare-match C

signal is generated. Note, however, that comparison is disabled during the T2 state of a TCORC

write cycle and a TICR input capture cycle.

TCORC is initialized to H'FF by a reset and in hardware standby mode.

The TCORC function is used in timer connection. For details, see section 13, Timer Connection.
