When using the charge pump, the LCDBIASx pins and the V
and the respective TRIS bits should be set as inputs.
CPEN: 3.6V Charge Pump Enable bit
1 = The regulator generates the highest (3.6V) voltage
0 = Highest voltage in the system is supplied externally (AV
Unimplemented: Read as ‘0’
BIAS<2:0>: Regulator Voltage Output Control bits
111 = 3.60V peak (offset on LCDBIAS0 of 0V)
110 = 3.47V peak (offset on LCDBIAS0 of 0.13V)
101 = 3.34V peak (offset on LCDBIAS0 of 0.26V)
100 = 3.21V peak (offset on LCDBIAS0 of 0.39V)
011 = 3.08V peak (offset on LCDBIAS0 of 0.52V)
010 = 2.95V peak (offset on LCDBIAS0 of 0.65V)
001 = 2.82V peak (offset on LCDBIAS0 of 0.78V)
000 = 2.69V peak (offset on LCDBIAS0 of 0.91V)
MODE13: 1/3 LCD Bias Enable bit
1 = Regulator output supports 1/3 LCD Bias mode
0 = Regulator output supports Static LCD Bias mode
CLKSEL<1:0>: Regulator Clock Select Control bits
11 = LPRC 31 kHz
10 = 8 MHz FRC
01 = SOSC
00 = Disable regulator and float regulator voltage output
