Operation example
Figure 9-2 shows a typical memory map, consisting of some memories, some simple peripher-
als, and a SAU with multiple channels and an Unlock Register (UR). Imagine that the MPU has
been set up to disallow all accesses from the CPU to the grey modules. Thus the CPU has no
way of accessing for example the Transmit Holding register in the UART, present on address X
on the bus. Note that the SAU RTRs are not protected by the MPU, thus the RTRs can be
accessed. If for example RTR0 is configured to point to address X, an access to RTR0 will be
remapped by the SAU to address X according to the algorithm presented above. By program-
ming the SAU RTRs, specific addresses in modules that have generally been protected by the
MPU can be performed.

9.5.5
Interrupts
The SAU can generate an interrupt request to signal different events. All events that can gener-
ate an interrupt request have dedicated bits in the Status Register (SR). An interrupt request will
be generated if the corresponding bit in the Interrupt Mask Register (IMR) is set. Bits in IMR are
set by writing a one to the corresponding bit in the Interrupt Enable Register (IER), and cleared
by writing a one to the corresponding bit in the Interrupt Disable Register (IDR). The interrupt
request remains active until the corresponding bit in SR is cleared by writing a one to the corre-
sponding bit in the Interrupt Clear Register (ICR).
The following SR bits are used for signalling the result of SAU accesses:
RTR Address Error (RTRADR) is set if an illegal address is written to the RTRs. Only
addresses in the range 0xFFFC0000-0xFFFFFFFF are allowed.
Master Interface Bus Error (MBERROR) is set if any of the conditions listed in Section 9.5.7
occurred.
