Note 1: SEG44, SEG45, and SEG46 exist only on PIC18F87J90 devices.
2: Disable SEG27, SEG28, SEG30, and SEG32 when the LCD module is enabled. Although SEG32 is
not listed in the diagram, it is multiplexed with the Timer1 oscillator, and therefore, must be disabled
when the Timer1 oscillator is enabled.
