6.2 Connection of INTR Pin
The INTR pin follows the N-channel open drain output logic and contains no protective diode on the power supply
side. As such, it can be connected to a pull-up resistor of up to 5.5 volts regardless of supply voltage.
6.3 Connection of 32KOUT Pin
As the 32KOUT pin is CMOS output, the voltages of the R
×
5C338A and any devices to be connected should be the
same. When the device is powered down, the 32KOUT output should be disabled.
When the CLKC pin is connected to the system power supply through the pull-up resistor, the pull-up resistor
should be 0
to 10k
, and the 32KOUT pin should be connect to the host through the resistor (approx. 10k
).

1) Depending on whether the INTR pin is to be used during bat-
tery backup, it should be connected to a pull-up resistor at the
following different positions:
1) Position A in the left diagram when it is not to be used during
battery backup.
2) Position B in the left diagram when it is to be used during
battery backup.
