THESE WIRES MAY BE LONG IF NECESSARY. IF
THE FUNCTION NEEDS TO BE CONFIGURABLE,
A SWITCH MAY BE ADDED BETWEEN THE
RESISTOR AND GROUND. THE SWITCHES MAY
BE LOCATED NEAR THE BACK PANEL.

is 0x8.
THIS CONNECTOR (XBUS) IS USED FOR SW DEVELOPMENT, FLASH PROGRAMMING, AND
CONNECTING WITH OTHER HW DEVELOPMENT PLATFORMS AND LOGIC ANALYZER.
Pull down resistor on AD4 allows
selection of 16/32 bit BootPromWidth.
AD[4] has internal pull up resistor.
Default= 32 bit ROM width.
selection of 16/32 bit BootPromWidth.
AD[4] has internal pull up resistor.
Default= 32 bit ROM width.
IMPORTANT NOTE !
THIS CONNECTOR IS MANDATORY ON THE FIRST REVISION OF THE BOARD TO
ALLOW SW DEVELOPMENT. WITHOUT THIS CONNECTOR IT IS IMPOSSIBLE TO
DEVELOP SW FOR THE CUSTOMER SPECIFIC APPLICATIONS. LATER, AFTER
THE DESIGN IS FINALIZED, THE CONNECTOR MAY BE REMOVED.
