REGISTER 21-6:
bit 2-0
Note 1:
respective TRIS bits should be set as inputs.
When using the external resistor ladder biasing, the LCDBIASx pins should be made analog and the
LRLAT<2:0>: LCD Reference Ladder A Time Interval Control bits
Sets the number of 32 clock counts when the A Time Interval Power mode is active.
For Type-A Waveforms (WFT = 0):
111 = Internal LCD reference ladder is in A Power mode for 7 clocks and B Power mode for 9 clocks
110 = Internal LCD reference ladder is in A Power mode for 6 clocks and B Power mode for 10 clocks
101 = Internal LCD reference ladder is in A Power mode for 5 clocks and B Power mode for 11 clocks
100 = Internal LCD reference ladder is in A Power mode for 4 clocks and B Power mode for 12 clocks
011 = Internal LCD reference ladder is in A Power mode for 3 clocks and B Power mode for 13 clocks
010 = Internal LCD reference ladder is in A Power mode for 2 clocks and B Power mode for 14 clocks
001 = Internal LCD reference ladder is in A Power mode for 1 clock and B Power mode for 15 clocks
000 = Internal LCD reference ladder is always in B Power mode
For Type-B Waveforms (WFT = 1):
111 = Internal LCD reference ladder is in A Power mode for 7 clocks and B Power mode for 25 clocks
110 = Internal LCD reference ladder is in A Power mode for 6 clocks and B Power mode for 26 clocks
101 = Internal LCD reference ladder is in A Power mode for 5 clocks and B Power mode for 27 clocks
100 = Internal LCD reference ladder is in A Power mode for 4 clocks and B Power mode for 28 clocks
011 = Internal LCD reference ladder is in A Power mode for 3 clocks and B Power mode for 29 clocks
010 = Internal LCD reference ladder is in A Power mode for 2 clocks and B Power mode for 30 clocks
