The TPnCCS1 bit setting is valid only in the free-running mode.
The TPnCCS0 bit setting is valid only in the free-running mode.

• The TPnOVF bit is reset when the 16-bit counter value overflows from FFFFH to 0000H in the free-
• An interrupt request signal (INTTPnOV) is generated as soon as TPnOVF bit is set (1).
• The TPnOVF bit is not cleared even when the TPnOVF bit and the TPnOPT0 register are read when
• The TPnOVF bit can be both read and written, but 1 cannot be written to the TPnOVF bit from the
TMPn option register 0 (TPnOPT0)
The TPnOPT0 register is an 8-bit register used to set the capture/compare operation and detect
overflow.
This register can be read and written in 8-bit or 1-bit units.
RESET input clears this register to 00H.

Rewrite TPnCCS1 and TPnCCS0 bits when TPnCE = 0 (the same value can be written
when TPnCE = 1.). If rewriting was mistakenly performed, clear TPnCE to 0 and then
set the bits again.
