A.6.1.1 PIM A Connector Pin Assignments
The PIM A connector is switch-selectable with the EIDE connector. On the back of
the Netra CP2300 cPSB board, there are three DIP switches: SW501, SW502, and
SW503. When all of the positions on SW501 and SW502, and positions 1 through 9
on SW503 are set to OFF, the EIDE connector is disabled and all of the PIM A
connector pins are available. When these switch positions are off, the EIDE
connector is active and PIM A J5 connector I/0 pins 1 to 29 (signals PMC_A_IO_1
through PMC_A_IO_29
)
are disabled and must be disconnected.
Refer to the Netra CP2300 cPSB Board Installation and Technical Reference Manual (816-
7186-xx) for more information about switch settings.
TABLE A-18
lists the pin assignments for the PIM A connector at J4, and
