ISINK2 Switch-On ramp
00 = instant (no ramp)
01 = 1 step every 4ms (220ms)
10 = 1 step every 8ms (440ms)
11 = 1 step every 16ms (880ms)
The time quoted in brackets is valid for the maximum
change in current drive setting. The actual time scales
according to the extent of the change in current drive
setting.
ISINK2 current.
Current = 2.0μA × 2^(CS2_ISEL/4), where CS2_ISEL
is an unsigned binary number.
Alternatively,
CS2_ISEL = 13.29 x LOG(current/2.0μA)
00_0000 = 2.0μA
11_0111 = 27.6mA
Values greater than 11_0111 will result in the maximum
current of approx 27.6mA.
