2.20.1 Bus Error Address Checks
When accessing peripherals on the PB-PIC® bus, an access beyond the implemented memory region 0x4401_FFFF causes the CPU to hang, waiting for a bus error signal.
Work Around:
Use the Microchip-provided peripheral drivers from Harmony 3 and the Microchip-provided SDK. This software will not generate addresses outside the implemented regions. If using third-party tools and other custom developed software, do not create accesses outside this region or an MCU Reset will be required to recover.
Note:
The work around is working in A2 and newer versions.
