17 e.g. timeout 20 sec will be rounded up to 32768 msec.
18 The maximum timeout period is 32 sec (32768 msec.),
19 Get time-left isn't supported
22 Actual HW timeout is defined in sec. and it's the same as
23 a user-defined timeout.
24 Maximum timeout is 255 sec.
25 Get time-left is supported.
28 Same as Type 2 with extended maximum timeout period.
