Register Map (continued)
Group #1 Target and Start Times Register (10h)
This register is used to set the duration that the backlights
will stay at the start value and at the target value. This
feature provides additional customization of the breathe
and blink lighting effects. Register 10h will only effect
banks that are assigned to group #1.
TT1_2, TT1_1, and TT1_0 [D5:D3]
These bits set the duration that backlights will stay at the
target value. These bits effect only banks assigned to
group #1. Target times are given in Table 18.
Table 18 — Target Time (Group #1)
Group #2 Target and Start Times Register (11h)
This register is used to set the duration that the backlights
will stay at the start value and at the target value. This
feature provides additional customization of the breathe
and blink lighting effects. Register 11h will only effect
banks that are assigned to group #2.
TT2_2, TT2_1, and TT2_0 [D5:D3]
These bits set the duration that backlights will stay at the
target value. These bits effect only banks assigned to
group #2. Target times are given in Table 20.
