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)
BIASMD: Bias Mode Select bit
When LMUX1:LMUX0 = 00:
0 = Static Bias mode (do not set this bit to ‘1’)
When LMUX1:LMUX0 = 01:
1 = 1/2 Bias mode
0 = 1/3 Bias mode
When LMUX1:LMUX0 = 10:
1 = 1/2 Bias mode
0 = 1/3 Bias mode
When LMUX1:LMUX0 = 11:
0 = 1/3 Bias mode (do not set this bit to ‘1’)
LCDA: LCD Active Status bit
1 = LCD driver module is active
0 = LCD driver module is inactive
WA: LCD Write Allow Status bit
1 = Write into the LCDDATAx registers is allowed
0 = Write into the LCDDATAx registers is not allowed
LP3:LP0: LCD Prescaler Select bits
1111 = 1:16
1110 = 1:15
1101 = 1:14
1100 = 1:13
1011 = 1:12
1010 = 1:11
1001 = 1:10
1000 = 1:9
0111 = 1:8
0110 = 1:7
0101 = 1:6
0100 = 1:5
0011 = 1:4
0010 = 1:3
0001 = 1:2
0000 = 1:1
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
