Cautions: 1. Rewrite bits TPnIS3 to TPnIS0 when TPnCE = 0 (the same value can be written
Remark:

TMPn dedicated I/O control register 1 (TPnIOC1)
The TPnIOC1 register is an 8-bit register that controls the valid edge for the external input signals
(TIPn0 and TIPn1).
This register can be read and written in 8-bit or 1-bit units.
RESET input clears this register to 00H.
