NOTES: A. In this diagram X(D) includes D31--D0 and XD31--XD0.
B. In this diagram, (X)A includes A23--A0 and XA12--XA0.
C. Control signals include STRB,MSTRB, and IOSTRB.
D. Asynchronous reset signals include XF1, XF0, CLKX0, DX0, FSX0, CLKR0, DR0, FSR0, CLKX1, DX1, FSX1, CLKR1, DR1, FSR1,
TCLK0, and TCLK1.
E. In microprocessor mode, the reset vector is fetched twice, with seven software wait states each time. In micromputer mode, the reset
vector is fetched twice, with no software wait states.
