Any attempt to write to the register when the outputs are enabled causes the command to

be ignored and the NOTPERF_CMD to rise (see Section 9.1.13).

9.1.7

TOFF_MIN

The TOFF_MIN register contains the minimum OFF time value used by the current control

system (see Section 7.1 for details).This parameter imposes the OFF time of the current

control system only if its value is greater than the TSW one.

The available range for both parameters is from 0.5 µs to 64 µs.

Any attempt to write to the register when the outputs are enabled causes the command to

be ignored and the NOTPERF_CMD to rise (see Section 9.1.13).
