MPC8314E Features
2.10
The integrated programmable interrupt controller (IPIC) provides a flexible solution for general-purpose
interrupt control. The IPIC programming model is compatible with the MPC8260 interrupt controller and
supports external and internal discrete interrupt sources. Interrupts can also be redirected to an external
interrupt controller.
2.11
The MPC8314E supports a range of power management states that significantly lower power consumption
under the control of the power management controller. The PMC includes the following features:
2.12
The serial peripheral interface (SPI) allows the MPC8314E to exchange data between other PowerQUICC
family chips, Ethernet PHYs for configuration, and peripheral devices such as EEPROMs, real-time
clocks, A/D converters, and ISDN devices.
The SPI is a full-duplex, synchronous, character-oriented channel that supports a four-wire interface
(receive, transmit, clock, and slave select). The SPI block consists of transmitter and receiver sections, an
independent baud-rate generator, and a control unit.
2.13
The integrated four-channel DMA controller includes the following features:

Support for Wake-on-Magic Packet™, a method to bring the device from standby to full operating
mode
MII management interface for external PHY control and status.
Provides power management when the device is used in both PCI host and agent modes
PCI Power Management 1.2 D0, D1, D2, D3hot, and D3cold states
PME generation in PCI agent mode, PME detection in PCI host mode
Wake-up from Ethernet (magic packet), USB, GPIO, and PCI (PME input as host) while in the D1,
D2 and D3hot states
A new low-power standby power management state called D3warm
— The PMC, one Ethernet port, and the GTM block remain powered via a split power supply
— Wake-up events include Ethernet (magic packet), GTM, GPIO, or IRQ inputs and cause the
— PCI agent mode is not be supported in D3warm state
PCI Express-based PME events are not supported
Allows chaining (both extended and direct) through local memory-mapped chain descriptors
(accessible by local masters)
