Description
DRA[1:0]x / DRB[1:0]x
DRn[1]x/DRn[0]x = 11 no Error
DRn[1]x/DRn[0]x = 10 Over Load, Shorted Load, Over temperature in
ON-Mode
DRn[1]x/DRn[0]x = 01 Open Load in OFF-Mode
DRn[1]x/DRn[0]x = 00 Short to GND in OFF-Mode
default DRx[1:0] = 11_B
A new error on the same channel will overwrite older information.
The diagnosis information which is returned by SO is latched when
CS makes a High-to-Low transistion of the frame which sends
out the register.
