(6) TMPn option register 0 (TPnOPT0)
Note Valid only for TMP0 and TMP2. Be sure to clear bits 5 and 4 of TMP1 and TMP3 to 0.
Cautions 1. Rewrite the TPkCCS1 and TPkCCS0 bits when the TPkCE bit = 0. (The same value can be
The TPnOPT0 register is an 8-bit register that sets the capture/compare operation and detects overflow.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
2. Be sure to clear bits 1 to 3, 6, and 7 to “0”.

to 0 and then set the bits again.

The TPkCCS1 bit setting is valid only in the free-running timer mode.
The TPkCCS0 bit setting is valid only in the free-running timer mode.
• The TPnOVF bit is set to 1 when the 16-bit counter value overflows from FFFFH
• An overflow interrupt request signal (INTTPnOV) is generated at the same time
• The TPnOVF bit is not cleared to 0 even when the TPnOVF bit or the TPnOPT0
• Before clearing the TPnOVF bit to 0 after generation of the INTTPnOV signal, be
