Part I. Overview
1.4 Differences between MPC860 and MPC8260
The following MPC860 features are not included in the MPC8260.
¥ 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)
¥ Asynchronous HDLC protocol (optional RAM microcode)
¥ 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)
