Function
3
LED LED drive (Open collector outputs)
4, 5
Rc, Cc Setting the oscillating frequency of the internal clocks.
6
Chg SW The SW drive terminal used for charging battery. (Open collector outputs)
7
GND Ground
8
Batt SW Checking whether a bettery is mounted or not. (It has a pull-up resistor)
9
VTR SW Detecting VTR connection. (It has a pull-up resistor)
10
Test Test mode set-up. (It has a pull-up resistor)
11
