9.5.2 Interval timer mode (TPnMD2 to TPnMD0 = 000B)
In the interval timer mode, an interrupt request signal (INTTPnCC0) is output upon a match between
the setting value of the TPnCCR0 register and the value of the 16-bit counter, and the 16-bit counter is
cleared. The TPnCCR0 register can be rewritten when TPnCE = 1, and when a value is set to the
TPnCCR0 register with a write instruction from the CPU, it is transferred to the CCR0 buffer register
through anytime write, and is used as the value for comparison with the 16-bit counter value.
In the interval timer mode, the 16-bit counter is cleared only upon a match between the value of the 16-
bit counter and the value of the CCR0 buffer register.
16-bit counter clearing using the TPnCCR1 register is not performed. However, the setting value of the
TPnCCR1 register is transferred to the CCR1 buffer register and compared with the value of the 16-bit
counter, and an interrupt request (INTTPnCC1) is output if these values match.
Moreover, TOPnm pin output is also possible by setting the TPnOEm bit to 1.
When the TPnCCR1 register is not used, it is recommended to set FFFFH as the setting value for the
TPnCCR1 register.
Remark:
n = 0 to 8
m = 0, 1

Note:
The 16-bit counter is not cleared upon a match between the 16-bit counter and TPnCCR1.
