16 bits of high-speed GPIO functionality connected to the processor’s local 32-bit bus
Memory-mapped device connected to the ColdFire core’s local 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 response
Data bits can be accessed directly or via alternate addresses to provide set, clear, and toggle
functions
— Alternate addresses allow set, clear, toggle functions using simple store operations without the
Unique data direction and pin enable control registers
Package pin toggle rates typically 1.5–3.5x faster than comparable pin mapped onto peripheral bus
need for read-modify-write references
