Figure 11
The ERR-flag will be set during over current shut down. It can be reset by reading the ERR-flag. If the channel is
still in over current shut down, the ERR-flag will be set again. During the automatic restart of the channel the ERR-
flag can be cleared by reading the ERR-flag. It will be set again as soon as the over current protection is activated
again.

The retry latch or over temperature latch is cleared by SPI command HWCR.CL = 1
the SPI register OUT is still set, the channel will be turned on immediately (or according to the automatic PWM
generator setting) after the command HWCR.CL = 1
