For diagnosis purpose, the SPOC - BTS5590G provides a current sense signal and the diagnosis word at SPI.
There is a current sense multiplexer implemented that is controlled via SPI. The sense signal can also be disabled
by SPI command. A switch bypass monitor allows to detect a short circuit between the output pin and the battery
voltage.
Please refer to
Figure 13
For diagnosis feedback at different operation modes, please see following table.

1) L = low level, H = high level, Z = high impedance, potential depends on leakage currents and external circuit x = undefined
2) The error flags are latched until they are transmitted in the standard diagnosis word via SPI
3) The over temperature flag is set latched and can be cleared by SPI command HWCR.CTL
