VCC1 Output for the real-time clock.
VCC2 Input for the time measurement function.
VCC2 Output for the waveform generation function.
VCC1 Input pins to control data transmission.
VCC1 Output pins to control data reception.
VCC1 Transmit/receive clock I/O.
VCC1 Serial data input.
VCC1 Serial data output. ⁽²⁾
VCC1 Output for the transmit/receive clock multiple-pin output function.
Notes:
1. Contact the oscillator manufacturer regarding the oscillation characteristics.
2. TXD2, SDA2, and SCL2 are N-channel open drain output pins. TXDi (i = 0, 1, 3 to 5), SDAi, and SCLi can be
selected as CMOS output pins or N-channel open drain output pins.
