logic
Input of display data of the shift register
Input from the MSB (positive logic).
Shift clock of the shift register.
Data is shifted at the falling edge of SCLK.
Latch clock input for display data.
When this pin is at a "H" level, the data is not latched to pass
through the latch circuit.
When the pin is at a "L" level, the data when the pin is at the
"H" level is latched.
Internal logic reset input upon power-on.
During reset, the 18-bit internal latch, duty cycle register,
digital register, LED register, and write/read address
register are all reset, and the outputs of SEGA to SEGP(*a),
D1 to D12 (*b), and LED1 to LED5 go off.
Connecting of an external capacitor to the pin allows power-
on reset.
