EVU Jumpers
JP4 and JP5 with R5 and R6 provide backward compatibility with the Flash Options on the Motorola MC68HC912B32
EVU Board. These can be installed by the user and the Debug12.s19 file programmed into the Internal Flash EPROM for
EVU similar operation of the development board. Normally this is not necessary due to the Utilities provided in the UTL12
EPROM's.

IN: enables RAM or EEPROM, 32K devices to U6/7
IN: enables RAM or EEPROM, 8K devices in U6/7
IN: enables EPROM, 8K or 32K devices in U6/7 (Default)
IN = U4/5 (SRAM) write enabled
OUT = U4/5 (SRAM) write disabled (write protect)
IN = External bus/memory devices enabled (U4/5/6/7 on if Expanded Mode)
OUT = External Memory disabled
JP2 must be IN for JP3 operation.
IN = External Memory Map: U4/5 = $0000-$7FFF and U6/7 = $8000 - $FFFF
OUT = External Memory Map: U4/5 = $0000 - $FFFF (U6/7 not in memory map)
IN = Flash Erase/Programming Voltage (VPP) is ON
OUT = Flash Erase/Programming Voltage (VPP) is OFF
Note: Expanded Narrow Mode not available.
Single Chip Mode (Internal Flash EEprom Boot)
Expanded Wide Mode (U4/5 or U6/7 Boot)
