18.4.4 RAM Control Register (RAMCR)
When the realtime programming of the user MAT is emulated, RAMCR sets the area of the user
MAT which is overlapped with a part of the on-chip RAM. RAMCR is initialized to H'F0 at a
power-on reset or in hardware standby mode and is not initialized in software standby mode. The
RAMCR setting must be executed in user mode or in user program mode.
For the division method of the user-MAT area, see table 18.7. In order to operate the emulation
function certainly, the target MAT of the RAM emulation must not be accessed immediately after
RAMCR is programmed. If it is accessed, the normal access is not guaranteed.
