Section 31 On-Chip RAM
31.2.3 Areas where Placing Instructions is Prohibited
Do not place instructions at the addresses within 16 bytes of the last address in the on-chip RAM
for data retention, i.e., at addresses H'FFFFBFF0 to H'FFFFBFFF. If an instruction is placed at
any of these prohibited locations, an overrun may cause the CPU to fetch from the address space
(H'FFFFC000 and subsequent addresses) for the on-chip peripheral modules, and this will lead to
an address error.
