Notes 1. When setting pins A0 to A15 as the alternate function, set all 16 bits of the PMC9 register to FFFFH at once.
2. The RXDA1 and KR7 pins must not be used at the same time. When using the RXDA1 pin, do not use the KR7 pin. When using the KR7 pin, do not use the RXDA1 pin (it
is recommended to set the PFC91 bit to 1 and clear the PFCE91 bit to 0).
