Using the MPMC8245 Card
in Standalone Mode
Gary Milliorn
CPD Applications
This application note describes modifications that may be performed to convert the
MPMC8245 ‘Unity’ MPMC or MPMC8241 ‘UnityLC’ MPMC cards in a Sandpoint system
to a standalone operation. An MPMC card normally resides in a Sandpoint motherboard, but
for COP emulator debugging, benchmarking, or other evaluation purposes, the card can be
removed and operated without a Sandpoint motherboard by making a few simple changes to
the board. This application note covers those changes and contains the following topics:

Clock
4. Program the standalone bus speed:
DINK32[MPC8245] {3} >> id -i
... (skip other questions)
STANDALONE BUS SPEED: 100
(or 66, 133, etc.)
... (skip other questions)
writing I2C @100
DINK32[MPC8245] {4} >>
(wait for EEPROM write)
5. Set the SW2 options switch on the MPMC8245 board to the following settings:
DN DN UP DN DN UP DN UP
(UP = toward the ‘ON’ switch)
Now, remove the MPMC board from the Sandpoint MPMC slot and continue with the conversion process.
5 Clock
The MPMC cards normally receive their clocks from the PCI clock on the PMC header. When operating as
a standalone board, an on-board clock source is required. The MPMC8245 boards supports a location to
install a 3.3-V oscillator, which should be installed at Y1. The oscillator may be any valid PCI bus
frequency, but 33 and 66 MHz are the fastest two standard speeds.
If the MPMC will ever be reinstalled in a Sandpoint system (which will be the case if the local flash needs
to be reprogrammed using the Sandpoint-based DINK), the oscillator must be removed or the Sandpoint
system will not work, and components on either board may be damaged. Using a socket is the easiest

The socket and oscillator are installed as shown in Figure 2. Note the orientation of pin 1 and install
appropriately.
