R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
C = Only clearable bit
bit 7
LCDEN:
LCD Driver Enable bit
1 = LCD driver module is enabled
0 = LCD driver module is disabled
0 = LCD driver module is disabled
