WUICR
RESET
This register configures the wake-up level for the L0, L1, and L2 inputs. It reports the CAN wake-up and SPI (CS) wake-up
WUISR
RESET
This register reads back the wake input (L0, L1, L2) causing the SBC to wake-up.
The information is SPIWU and BUSWU is latched. Bits SPIWU and BUSWU will be reset by a read operation of the WUICR
$00C

0 = No failure on TX
1 = TX permanent dominant
1 = Ground shift above the threshold selected by GSLR1 and GSLR2
0 = No ground shift
The SHIFT information is latched until a read operation of the GSLR register occurs. The GSLR register is set to 0 after power-ON
reset. A reset of GSLR1 and GSLR0 occurs when RST = Low.
