18.4.11 Address Space Priority

The host addresses can be specified from H'00000000 to H'FFFF0000 by the settings of HBAR1,
HBAR2, and RAMBAR. The host address spaces, however, may be overlapped depending on the
ASSR setting. Moreover, the slave address spaces may be overlapped depending on the settings of
SAR1, SAR2, and ASSR. For this, individual address spaces are given priority. The priority is as
follows:
Command space > address space 1 > on-chip RAM space > address space 2
Notes: 1. Please keep in mind that the slave on-chip RAM space may be overlapped with the
RBUFAR space.
2. Only the flash memory can be accessed in address spaces 1 and 2.
