Section 20 Flash Memory (0.18-µm F-ZTAT Version)
20.6.3
RAMER specifies the user MAT area overlaid with part of the on-chip RAM (H'FFA000 to
H'FFAFFF) when performing emulation of programming the user MAT. RAMER should be set in
user mode or user program mode. To ensure dependable emulation, the memory MAT to be
emulated must not be accessed immediately after changing the RAMER contents. When accessed
at such a timing, correct operation is not guaranteed.

Flash Memory Area Select
These bits select the user MAT area overlaid with the
on-chip RAM when RAMS = 1. The following areas
correspond to the 4-kbyte erase blocks.
