AMI Write
Use these specifications for asynchronous interfacing to memo-
ries. Note that timing for AMI_ACK, ADDR, DATA, AMI_RD,
AMI_WR, and strobe timing parameters only apply to asyn-
chronous access mode.

W = (number of wait states specified in AMICTLx register) × tSDCLK
H = (number of hold cycles specified in AMICTLx register) × tSDCLK
1 AMI_ACK delay/setup: System must meet tDAAK, or tDSAK, for deassertion of AMI_ACK (low).
2 The falling edge of MSx is referenced.
3 Note that timing for AMI_ACK, AMI_RD, AMI_WR, and strobe timing parameters only applies to asynchronous access mode.
4 See Test Conditions on Page 55 for calculation of hold times given capacitive and dc loads.
5 For Write to Write: tSDCLK + H, for both same bank and different bank. For Write to Read: 3 × tSDCLK + H, for the same bank and different banks.
