BAM
Address mask. Masks equivalent CSOR[BA] bits. The BAM setting chooses which BA bits to compare
with the corresponding address bit to determine a match.
0 Mask address bit
1 Compare address bit
Address setup enable. Controls assertion of chip select with respect to assertion of a valid address that
hits in the chip select address space.
0 Assert chip select on the rising edge of CLK that address is asserted.
1 Delay assertion of chip select for one CLK cycle after address is asserted. During write transfers,
R/W asserts 1 clock cycle after assertion of the chip select.
Controls the address, data, and attribute hold time after the termination, internal or external with TA, of
a write cycle that hits in the chip select address space.
0 Do not hold address, data, and attribute signals an extra cycle after chip select and R/W negate on
1 Hold address, data, and attribute signals an extra cycle after CSx and R/W negate on writes.
