EP9315
Enhanced Universal Platform SOC Processor
Note:
Port F defaults as PCMCIA pins. Port F must be
configured by software to be used as GPIO.
Reset and Power Management
The chip may be reset through the PRSTn pin or through
the open drain common reset pin, RSTOn.
Clocks are managed on a peripheral-by-peripheral basis
and may be turned off to conserve power.
The processor clock is dynamically adjustable from 0 to
200 MHz (184 MHz for industrial conditions).
Hardware Debug Interface
The JTAG interface allows use of ARM’s Multi-ICE or
other in-circuit emulators.
Note:
The JTAG interface does not support boundary scan.
Internal Boot ROM
The Internal 16-kbyte ROM allows booting from FLASH
memory, SPI or UART. Consult the EP93xx User’s
Manual for operational details
12-channel DMA Controller
The DMA module contains 12 separate DMA channels.
Ten of these may be used for peripheral-to-memory or
memory-to-peripheral access. Two of these are
dedicated to memory-to-memory transfers. Each DMA
channel is connected to the 16-bit DMA request bus.
The request bus is a collection of requests, Serial Audio,
and UARTs. Each DMA channel can be used
independently or dedicated to any request signal. For
each DMA channel, source and destination addressing
can be independently programmed to increment,
decrement, or stay at the same value. All DMA
addresses are physical, not virtual addresses.
PCMCIA Interface
The EP9315 has a single PCMCIA port which can be
used to access either 8 or 16-bit devices.
