SYSCR2 is an 8-bit readable/writable register that enables or disables write to the on-chip RAM.
SYSCR2 is initialized to H'FF by a power-on reset or in deep standby mode but retains its
previous value by a manual reset or in software standby mode. Only byte access is valid.
When an RAMWE bit is set to 1, the corresponding on-chip RAM area is enabled. When an
RAMWE bit is cleared to 0, the corresponding on-chip RAM area cannot be written to. In this
case, writing to the on-chip RAM is ignored. The initial value of an RAMWE bit is 1.
Note that when clearing the RAMWE bit to 0 to disable the on-chip RAM, be sure to execute an
instruction to read from or write to the same arbitrary address in each page before setting the
RAMWE bit. If such an instruction is not executed, the data last written to each page may not be
written to the on-chip RAM. Furthermore, an instruction to access the on-chip RAM should not be
placed immediately after the instruction to write to SYSCR2. If an on-chip RAM access
instruction is set, normal access is not guaranteed.
Note: When writing to this register, see section 25.4, Usage Note.
