Cautions 1. If bit 1 (PIOR1) of the PIOR register is set to 1, the TxD2 and RxD2 pins are redirected, but SCL20,
SDA20, SI20, SO20, SCK20 pins are not redirected. Therefore, IIC20 and CSI20 cannot be used in
its setting. However, even if the bit is set to 1, CSI21/IIC21 can be used by P70 to P72 if UART2 is
not used.
2. For 20- to 25-pin products, PIOR register is not mounted.
