25.2.3 Master to Slave Access
All the Masters can normally access all the Slaves. However, some paths do not make sense, for example
allowing access from the Cortex-M4 S Bus to the Internal SRAM. Thus, these paths are forbidden or simply not
wired, and shown as “
–” in Table 25-2.
Slave 3 Peripheral Bridge 0
Slave 4 Peripheral Bridge 1
