Logic Equations --- Min Term Equations
The test input and output pins are related by the following equations, where INV denotes a logical inversion
operation and XOR a logical exclusive OR operation:
MT0 = XOR (A1, A6, PAR)
MT1 = XOR (A8, ALERT#, A9)
MT2 = XOR (A2, A5, A13)
MT3 = XOR (A0 A7, A11)
MT4 = XOR (CK#, ODT, CAS#/A15)
MT5 = XOR (CKE, RAS#/A16, A10/AP)
MT6 = XOR (ACT#, A4, BA1)
MT7 = XOR (x16: UDM#/UDBI#, LDM#/LDBI#, CK)
MT8 = XOR (WE#/A14, A12/BC#, BA0)
MT9 = XOR (BG0, A3, RESET# and TEN)
