4.2 Memory Map during Debug Board Connection
Table 4.2 shows a memory map for the SH7760 when the debug board is connected to the Solution Engine2
board and the jumper switch (J1) on the debug board is short-circuited. Table 4.2 also shows a memory map
for the SH7760 when the debug board is connected to the Solution Engine2 board and the jumper switch (J1) on
the debug board is open.
