Connection Points
As the PRUB must be the bottom board, it is difficult to access PRUB eyelets from the board’s top
surface. You may find it easier to access the eyelets from the bottom surface. Table 5-1 lists port
eyelets, as they appear from the bottom of the PRUB, by both J numbers and port lines.
The J7 eyelets are connection points for the CSE1_MAPI signal. Similarly, the J19 eyelets are
connection points for the CSE0_MAPI signal. Each of these signals has one of four coded values,
according to the assertion levels of two lines. You may connect to the J7 or J19 eyelets to read these
assertion levels.
