1.4 Differences between MPC860 and PowerQUICC II
The following MPC860 features are not included in the PowerQUICC II.
• On-chip crystal oscillators (must use external oscillator)
• 4-MHz oscillator (input clock must be at the bus speed)
• Low power (stand-by) modes
• Battery-backup real-time clock (must use external battery-backup clock)
• BDM (COP offers most of the same functionality)
• True little-endian mode
• PCMCIA interface
• Infrared (IR) port
• QMC protocol in SCC (256 HDLC channels are supported by the MCCs)
• Multiply and accumulate (MAC) block in the CPM
• Centronics port (PIP)
• Pulse-width modulated outputs
• SCC Ethernet controller option to sample 1 byte from the parallel port when a receive frame is
complete
• Parallel CAM interface for SCC (Ethernet)
