DESCRIPTION
Chip select
Clocks shift register on negative edge and DOUT pins on positive edge
Segment outputs equal shift register data if Load is high
Shift register data input
Display clock input and is always bonded out. Can swing from VEE to VDD
Bonded out only if an RC oscillator is required
Selected pinout can provide shift register taps at positions 30, 32, 34, or 38
Low resistance drive for the backplane and swings from VDD to VEE
High resistance drive for each segment and swings from VDD to VEE
