Note1: When setting <PP3F2, PP2F2, PP1F2> = "1", PP3 ~ PP5 pins are set to SIO0 or SIO1 functions regardless
PPCR, PPFC setting. PP3 is set to TXD, PP4 is set to RXD. PP5 is set to SCLK input or CTS input when
<PP5C> = 0. PP5 is set to SCLK output when <PP5C> = 1.
Note2: A read-modify-write operation cannot be performed for the registers PPCR, PPFC.
Note3: When setting PP5, PP4, PP3 pins to INT7,INT6,INT5 input, set PPDR<PP5D:3D> to "0000" (prohibit input),
and when driving PP5,PP4,PP3 pins to "0", execute HALT instruction. This setting generates INT7, INT6, and
INT5 inside. If don't using external interrupt in HALT condition, set like an interrupt don't generated.
