8.5
There is a separate interface for the program flash and data
flash memories. The same set of registers exist in both in-
terfaces. In most cases they are independent of each other,
but in some cases the program flash interface controls the
interface for both memories, as indicated in the following
sections. Table 18 lists the registers.

8.5.1
The FMIBAR register specifies the 8-bit address for read or
write access to an information block. Because only word ac-
cess to the information blocks is supported, the least signif-
icant bit (LSB) of the FMIBAR must be 0 (word-aligned). The
hardware automatically clears the LSB, without regard to
the value written to the bit. The FMIBAR register is cleared
after device reset. The CPU bus master has read/write ac-
cess to this register.

The Information Block Address field holds the
word-aligned address of an information block
location accessed during a read or write
transaction. The LSB of the IBA field is always
clear.
