Input Realtime clock oscillator input/output pins.
Output Connect a 32.768 kHz crystal. If 32.768 kHz
crystal oscillation is not used, fix the ×1 pin to
VCC and leave the ×2 pin open.
I/O I/O pins addressed bit by bit. D0 to D3 are
large-current source pins (max. 10 mA), and
D to D are large-current sink pins (max. 15
