Reset
There are several reset trigger implemented in the device. A reset switches off all channels and sets the registers
to default values. After any kind of reset, the transmission error flag (TER) is set.
Under Voltage Reset:
During this device condition a read on SPI always delivers the Standard Diagnostic Frame with a TER flag.
This under voltage reset is released when all the supply voltages levels are above under voltage threshold.
Reset Command: There is a reset command available to reset all register bits of the register bank and the
diagnosis registers. As soon as CMD.RST = 1, a reset is triggered.
Limp Home Mode: In limp home mode, the SPI write-registers are reset. The SPI interface is operating normally,
so the limp home bit LHI as well as the diagnosis flags can be read, but no command is accepted until the device
leaves the Limp home operation.
