11. Advanced Timer Unit-II (ATU-II)
• Bit 3—Clear Counter Enable Flag 3A, 4A, 5A, 3C, 4C, 5C (CCI3A, CCI4A, CCI5A, CCI3C, CCI4C, CCI5C): These
bits select enabling or disabling of free-running counter (TCNT) clearing.
Bit 3: CCIxx
Description
0
TCNT clearing disabled
1
TCNT cleared on GR compare-match
Note: xx = 3A, 4A, 5A, 3C, 4C, or 5C
(Initial value)
TCNT is cleared on compare-match only when GR is functioning as an output compare register.
• Bits 2 to 0—I/O Control 3A2 to 3A0, 4A2 to 4A0, 5A2 to 5A0, 3C2 to 3C0, 4C2 to 4C0, 5C2 to 5C0 (IO3A2 to
IO3A0, IO4A2 to IO4A0, IO5A2 to IO5A0, IO3C2 to IO3C0, IO4C2 to IO4C0, IO5C2 to IO5C0): These bits select the
general register (GR) function.

cannot be written to)
Input capture in GR on rising edge at TIOxx
pin (GR connot be written to)
Input capture in GR on falling edge at TIOxx
pin (GR connot be written to)
Input capture in GR on both rising and falling
edges at TIOxx pin (GR connot be written to)

TIOR11 specifies whether general registers GR11A and GR11B are used as input capture or compare-match registers, and
also performs edge detection and output value setting.
TIOR11 is initialized to H'00 by a power-on reset, and in hardware standby mode and software standby mode.
• Bit 7—Reserved: This bit is always read as 0. The write value should always be 0.
