Caution The transmit/receive operation of UARTA2 and I
To use the I
P91/SCL02 pins as the serial transmit/receive data I/O pins (SDA00 to SDA02) and serial clock I/O pins
(SCL00 to SCL02), respectively, and set them to N-ch open-drain output
switched during transmission or reception. Be sure to disable the one that is not used.
