MC2 chip LCSR (Local Control/Status Register). The bit values are read as a zero when the jumper is installed and as a one when the jumper is removed.

If the MVME162Bug firmware is removed, seven jumpers are user-definable (pins 1-2, 3- 4, 5-6, 7-8, 11- 12, 13-14, 15-16). Note Pins 9-10 (GPI3) are reserved to select either the flash memory map (jumper installed) or the EPROM memory map (jumper removed). They are not user-definable. Refer to Chapter 3 for additional information. In most cases, the controller is shipped from the factory with J22 set to all zeros (jumpers installed on all pins). On controller boards built with the no-VMEbus option, however, there is no jumper is installed across pins 9- 10.

Default factory configuration is with no jumper installed. IP Bus Clock Header (J24) This header selects the speed of the IP bus clock. The IP bus clock speed may be 8MHz (on both MVME162-4xx and -5xx boards) or 32MHz (on MVME162-5xx boards only). The default factory configuration is with a jumper installed on J24, pins 1 and 2 denoting an 8MHz clock. If the jumper is installed on J24, between pins 2 and 3, the IP bus clock is the same as the MC68040 bus clock (32MHz), thus allowing the IP module to run with a 32MHz MPU. Whether the setting is 8MHz or 32MHz, all IP ports operate at the same speed. ! Caution The IP32 CSR bit (IP2 chip, register at offset $1D, bit 0) must be set to correspond to the jumper setting. This is cleared (0) for 8MHz, or set (1) for 32MHz. If the jumper and the bit are not configured the same, the board may not run properly. 1 2 (Factory configuration) J23 Not used 3 2 1 3 2 1 (Factory configuration) J24 8MHz IP Bus Clock J24 32MHz IP Bus Clock (from MPU Bus Clock) 2-14 Computer Group Literature Center Web Site Hardware Preparation 2 Note Some versions of the controller (those identified with assembly number 01-W3960Bxxx) may have J24 factoryhardwired in the 8MHz position with a staple between J2 pins 1 and 2, hidden beneath an IP module. Changing the factory setting to the 32MHz setting requires removal of the staple between pins 1 and 2, and installation of a jumper between pins 2 and 3. IP Bus Strobe Select Header (J25) Some IP bus implementations make use of the Strobe∗ signal (pin 46) as an input to the IP modules from the IP2 chip. Other IP interfaces require that the strobe be disconnected. With a jumper installed between J25 pins 1 and 2, a programmable frequency source is connected to the Strobe∗ signal on the IP bus. Refer to the IP2 chip programming model in the MVME162FX Embedded Controller Programmer’s Reference Guide for additional information. If the jumper is removed from J25, the strobe line is available for a sideband type of messaging between IP modules.
