LBWST0 - LCD Bus Interface wait state register
The 8-bit LBWST0 register determines the number of wait states of the LCD
Bus Interface. The number of wait states defines the duration of the DBWR
and DBRD signals. This duration must remain below the cycle time.
This register can be read/written in 8-bit or 1-bit units.
