9.3.6 LCD Status Register (LCDS)
Read: anytime
Write: anytime
9.3.7 LCD Pin Enable Registers 0–5 (LCDPEN0–LCDPEN5)
When LCDEN = 1, these bits enable the corresponding LCD pin for LCD operation.
These registers should only be written with instructions that perform byte writes, using instructions that
perform word writes will lead to invalid data being placed in the register. Initialize these registers before
enabling the LCD module. Exiting stop2 mode does not require reinitializing the LCDPEN registers.
