Registers
Note 1: These are not directly connected to the I/O pads, but may be tri-stated, depending on the
configuration of the LCD module.
2: SEG<23:0> on PIC16F914/917, SEG<15:0> on PIC16F913/916.
3: COM3 and SEG15 share the same physical pin on the PIC16F913/916, therefore SEG15 is
not available when using 1/4 multiplex displays.
