Timer I/O Control Register 10 (TIOR10): TIOR10 is an 8-bit readable/writable register that

selects the value for multiplication of the external input (TI10) edge interval. It also makes a

setting for using the general register (GR10G) for output compare, and makes the edge detection

setting.

TIOR10 is initialized to H'00 by a power-on reset, and in hardware standby mode and software

standby mode.

• Bit 7—Reload Enable (RLDEN): Enables or disables transfer of the input capture register 10A

(ICR10A) value to reload register 10C (RLD10C).

Bit 7: RLDEN

Description

Transfer of ICR10A value to RLD10C on input capture is enabled

(Initial value)

Transfer of ICR10A value to RLD10C on input capture is disabled

• Bit 6—Counter Clock Select (CCS): Selects the operation of correction counter 10E

(TCNT10E). Set the multiplication factor with bits PIM1 and PIM0.

Bit 6: CCS

Description

TCNT10E count is not halted when TCNT10D x multiplication factor =

TCNT10E*

(Initial value)

TCNT10E count is halted when TCNT10D x multiplication factor = TCNT10E*

Note: * When [TCNT10D

× multiplication factor] matches the value of TCNT10E with bits 8 to 0

masked.

• Bits 5 and 4—Pulse Interval Multiplier (PIM1, PIM0): These bits select the external input

(TI10) cycle multiplier.

Bit 5: PIM1

Bit 4: PIM0
