SCL
Serial Clock (SCL).
The input buffer on this pin is always active (not gated). Disabled when the backup
power supply on the V
BAT
pin is activated.
Interrupt Output – IRQ, Frequency Output– FOUT.
configuration register that can be used as interrupt or frequency output pin.
Interrupt Mode. This is an interrupt signal output. This signal notifies a host processor
that an alarm has occurred and requests action. It is an open drain active low out-
put.This mode is selected via the frequency out control bits.
Frequency Output Mode. This is an frequency output pin. The frequency output is user
selectable and enabled via the 2-wire bus. This mode is selected via the frequency out
control bits.
Chip supply pin.
The SCL input is used to clock all data into and out of the device.
