PeripAccessCapability
This parameter defines the capabilities of the peripheral. It is the sum of the values of
the individual capabilities (see Table 4-6).
For example:
• A value of
0x20020 means that the peripheral can handle word data accesses, but
not bytes, halfwords, or double words, and understands the Endian signal. This
value is predefined as
PeripAccessCapability_Minimum .
• A value of
0x20038 means that the peripheral can handle byte, halfword, and word
data accesses, but not doubleword, and understands the Endian signal. This value
is predefined as
PeripAccessCapability_Typical .
