R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
WFT: Waveform Type Select bit
1 = Type-B waveform (phase changes on each frame boundary)
0 = Type-A waveform (phase changes within each common type)
1 = Type-B waveform (phase changes on each frame boundary)
0 = Type-A waveform (phase changes within each common type)
bit 6
BIASMD: Bias Mode Select bit
When LMUX<2:0> = 000 or 011 through 111:
0 = Static Bias mode (LMUX<2:0> = 000) / 1/3 Bias mode (LMUX<2:0> = 011 through 111) (do not
When LMUX<2:0> = 000 or 011 through 111:
0 = Static Bias mode (LMUX<2:0> = 000) / 1/3 Bias mode (LMUX<2:0> = 011 through 111) (do not
set this bit to ‘1’)
When LMUX<2:0> = 001 or 010:
1 = 1/2 Bias mode
0 = 1/3 Bias mode
1 = 1/2 Bias mode
0 = 1/3 Bias mode

1 = LCD driver module is active
0 = LCD driver module is inactive
1 = LCD driver module is active
0 = LCD driver module is inactive
bit 4
WA: LCD Write Allow Status bit
1 = Writes into the LCDDATAx registers is allowed
0 = Writes into the LCDDATAx registers is not allowed
1 = Writes into the LCDDATAx registers is allowed
