Ordering Information
25.6
Configuration Pin Multiplexing
The MPC8314E provides the user with power-on configuration options that can be set through the use of
external pull-up or pull-down resistors of 4.7 k
Ω on certain output pins (see customer visible configuration
pins). These pins are generally used as output only pins in normal operation.
While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins
while HRESET is asserted, is latched when PORESET deasserts, at which time the input receiver is
disabled and the I/O circuit takes on its normal function. Careful board layout with stubless connections
to these pull-up/pull-down resistors coupled with the large value of the pull-up/pull-down resistor should
minimize the disruption of signal quality or speed for output pins thus configured.
25.7
Pull-Up Resistor Requirements
The MPC8314E requires high resistance pull-up resistors (10 k
Ω is recommended) on open drain type pins
including I2C pins, Ethernet Management MDIO pin and EPIC interrupt pins.
For more information on required pull up resistors and the connections required for JTAG interface, see
AN3438, MPC8315 Design Checklist

Part Numbers Fully Addressed by this Document
Table 77 provides the Freescale part numbering nomenclature for the MPC8314E. Note that the individual
part numbers correspond to a maximum processor core frequency. For available frequencies, contact your
local Freescale sales office. In addition to the processor frequency, the part numbering scheme also
includes an application modifier which may specify special application conditions. Each part number also
contains a revision code which refers to the die mask revision number.
