bit 0

Legend:

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

bit 7-6

LRLAP<1:0>: LCD Reference Ladder A Time Power Control bits

During Time interval A (Refer to Figure 21-4):

= Internal LCD Reference Ladder is powered down and unconnected

= Internal LCD Reference Ladder is powered in low-power mode

= Internal LCD Reference Ladder is powered in medium-power mode

= Internal LCD Reference Ladder is powered in high-power mode

bit 5-4

LRLBP<1:0>: LCD Reference Ladder B Time Power Control bits

During Time interval B (Refer to Figure 21-4):

= Internal LCD Reference Ladder is powered down and unconnected

= Internal LCD Reference Ladder is powered in low-power mode

= Internal LCD Reference Ladder is powered in medium-power mode

110

= Internal LCD Reference Ladder is in ‘A’ power mode for 6 clocks and ‘B’ power mode for 10 clocks

111

= Internal LCD Reference Ladder is in ‘A’ power mode for 7 clocks and ‘B’ power mode for 9 clocks

For type B waveforms (WFT = 1):

000

= Internal LCD Reference Ladder is always in ‘B’ power mode.

001

= Internal LCD Reference Ladder is in ‘A’ power mode for 1 clock and ‘B’ power mode for 31 clocks

010

= Internal LCD Reference Ladder is in ‘A’ power mode for 2 clocks and ‘B’ power mode for 30 clocks

011

= Internal LCD Reference Ladder is in ‘A’ power mode for 3 clocks and ‘B’ power mode for 29 clocks

100

= Internal LCD Reference Ladder is in ‘A’ power mode for 4 clocks and ‘B’ power mode for 28 clocks

101
