0569: 24 columns, no DATA OUT pin, display blank has no effect
0530: specifications unknown, pinout seems similar to 0569

HLCD 0569 doesn't have DATA OUT, instead it has what seems like OSC OUT on pin 34.

OSC is tied to a capacitor, the result frequency is 50000 * cap(in uF), eg. 0.01uF cap = 500Hz.
Internally, this is divided by 2, and by number of rows to get display refresh frequency.
