1) L = low level, H = high level, Z = high impedance, potential depends on leakage currents and external circuit.
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 (in OFF states also) and can be cleared by SPI command HWCR.CTL.
8.1
The standard diagnosis at the SPI interface provides information about each channel. The error flags, an OR
combination of the over temperature flags and the over load monitoring signals are provided in the SPI standard
diagnosis bits ERRn.
The over load monitoring signals are latched in the error flags and cleared each time the standard diagnosis is
transmitted via SPI. In detail, they are cleared between the second and third raising edge of the SCLK signal.
The over temperature flags, which cause an overheated channel to latch off, are latched directly at the gate control
block. The latches are cleared by SPI command HWCR.CTL.
Please note: The over temperature information is latched twice. When transmitting a clear thermal latch command
(HWCR.CTL), the error flag is cleared during command transmission of the next SPI frame and ready for latching
after the third raising edge of the SCLK signal. As a result, the first standard diagnosis information after a CTL
command will indicate a failure mode at the previously affected channels although the thermal latches have been
cleared already. In case of continuous over load, the error flags are set again immediately because of the over
load monitoring signal.
