This bit is cleared when the operation is completed and no SAU bus operations are pending.
This bit is set when a read or write operation to the SAU channel is started.
This bit is cleared when the SAU exits setup mode.
This bit is set when the SAU enters setup mode.
This bit is cleared when the SAU is disabled.
This bit is set when the SAU is enabled.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set if, in the configuration phase, an RTR was written with an illegal address, i.e. the upper 16 bits in the address were
different from 0xFFFC, 0xFFFD, 0xFFFE or 0xFFFF.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set if a channel access generated a transfer on the master interface that received a bus error response from the
addressed slave.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set if an attempt was made to unlock a channel by writing to the Unlock Register while one or more error bits were set
in SR. The unlock operation was aborted.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set if the Unlock Register was attempted written with an invalid key.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set if the Unlock Register was read.
