Lock register protection from runaway software
Reset generation logic with an enable/disable
User-enabled stalling when the controller asserts the CPU Halt flag during debug
Master or slave operation
Programmable clock bit rate and prescale
Separate transmit and receive FIFOs, 16 bits wide, 8 locations deep
Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
Programmable data frame size from 4 to 16 bits
