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.

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.
