30.2.1.5 SKHA Error Status Register (SKESR)
The read-only SKESR indicates the type of error that has occurred. These errors are described
below and shown in
interrupt request to the interrupt controller. If multiple errors occur, only the first error will be
flagged. The SKHA must be reset when any error occurs. A write to this register has no effect.
