DESCRIPTION
Current dissipation time. This bit is the time allowed for the current to dissipate
from the actuator between PWM cycles for flyback mitigation. (Advanced use
only)
the current dissipation time for LRA has an additional 2 bits (IDISS_TIME[3:2])
located in register 0x1F. Depending on the status of N_ERM_LRA the idiss time
represents different values
N_ERM_LRA = 0 (ERM mode)
0: 45 µs
1: 75 µs
2: 150 µs
3: 225 µs
N_ERM_LRA = 1(LRA mode)
0: 15 µs
1: 25 µs
2: 50 µs
3: 75 µs
4: 90 µs
5: 105 µs
6: 120 µs
7: 135 µs
8: 150 µs
9: 165 µs
10: 180 µs
11: 195 µs
12: 210 µs
13: 235 µs
14: 260 µs
15: 285 µs
