NOTES: A. The mapping of XINTF Zone 7 is dependent on the XMP/MC device input signal and the MP/MC mode bit (bit 8 of XINTCNF2
register). Zones 0, 1, 2, and 6 are always enabled.
B. Each zone can be programmed with different wait states, setup and hold timing, and is supported by zone chip selects
(XZCS0AND1, XZCS2, XZCS6AND7), which toggle when an access to a particular zone is performed. These features enable
glueless connection to many external memories and peripherals.
C. The chip selects for Zone 0 and 1 are ANDed internally together to form one chip select (XZCS0AND1). Any external memory
that is connected to XZCS0AND1 is dually mapped to both Zones 0 and Zone 1.
D. The chip selects for Zone 6 and 7 are ANDed internally together to form one chip select (XZCS6AND7). Any external memory
that is connected to XZCS6AND7 is dually mapped to both Zones 6 and Zone 7. This means that if Zone 7 is disabled (via the
MP/MC mode) then any external memory is still accessible via Zone 6 address space.
E. XCLKOUT is also pinned out on the 2810 and 2811.
