The following improvements were made to create the 1L05H mask set
(MC68HC912Dx128C) and the 2L05H mask set (MC68HC912Dx128P).
Previous MC68HC912DT128A mask sets 3K91D (TSMC wafer fab.)
and 0L05H (Motorola TSC6 wafer fab.) are equivalent with the only
change being the wafer fab location.
The following are the primary differences between the previous Colpitts
("A") and the new Colpitts ("C") oscillator configurations.
1. Optimisation of the bias current to the amplifier for less process
2. Addition of hysteresis to the clock input buffer to reduce sensitivity
