Used as power supply pin for low level LCD drive.
Used as logic system power supply pin.
Used as vertical shift clock pulse input pin.
Used as vertical scanning start pulse input/output pins.
Data input/output pins for shift register. During input, data is read at the rising edge of the
CKV. During output, data is output at the falling edge of the CKV.
When R/L = "H".
SVOI is set to data output pin for next cascade, and SVIO is set to input pin for shift data.
When R/L = "L".
SVOI is set to input pin for shift data, and SVIO is set to data output pin for next cascade.
Used as input pin for selecting the shift direction of bi-directional shift register and for
setting the sequence of cascade connection.
LCD drive outputs shift from OG
