• Data bits can be accessed directly or via alternate addresses to provide set, clear, and
• Unique data direction and pin enable control registers
• Package pin toggle rates typically 1.5–3.5x faster than comparable pin mapped onto
toggle functions
peripheral bus
• Support for all access sizes: byte, word, and longword
• All reads and writes complete in a single data phase cycle for zero wait-state
• Alternate addresses allow set, clear, toggle functions using simple store
response
operations without the need for read-modify-write references
