... Freescale Semiconductor, Inc. ON-CHIP PERIPHERALS To improve total system throughput and reduce part count, board size, and cost of system implementation, the M68300 family integrates on-chip, intelligent peripheral modules and typical glue logic. These functions on the MC68340 include the SIM40, a DMA controller, a serial module, and two timers. ...

... Freescale Semiconductor, Inc. Clock Synthesizer The clock synthesizer generates the clock signals used by all internal operations as well as a clock output used by external devices. The clock synthesizer can operate with an inexpensive 32768-Hz watch crystal or an external oscillator for reference, using an internal phase-locked loop and voltage-controlled oscillator. At any time, software can select clock frequencies from 131 kHz to 16 ...

... Freescale Semiconductor, Inc. In dual-address mode, two bus transfers occur, one from a source device and the other to a destination device. Dual-address transfers can be started by either an internal or external request. In this mode, each channel supports 32 bits of address and bits of data (32 bits require external logic). The source and destination port size can be selected independently ...
