From the first link on the web-page you linked to
http://digital-wizard.net/avr_projects/p10_led_display_panel_interface
- EN (Enable) is used for PWM brightness control of the entire panel. That means the MCU can control the brightness by feeding a pulse width modulated signal on this pin.
- A & B are the multiplex select pins. They take binary input to select any one of the four multiplex rows.
- Shift clock, Store clock and Data are the normal shift register control pins. The shift register IC used is IC74HC595
