O VCC1 Output for the transmit/receive clock multiple-pin output function.
Notes:
1. Contact the manufacturer of crystal/ceramic resonator regarding the oscillation characteristics.
2. TXD2, SDA2, and SCL2 are N-channel open drain output pins. TXDi (i = 0, 1, 5 to 7), SDAi, and SCLi can be
selected as CMOS output pins or N-channel open drain output pins.
