ACLK duty cycle, t
AC1J1V1 setup time before ACLK
AC1J1V1 hold time after ACLK
ASPE setup time before ACLK

A(7-0)/APAR data /parity out valid delay from ACLK
A(7-0)/APAR data /parity to tristate delay from ACLK
ADD add indicator delayed from ACLK
A(7-0)/APAR data /parity out tristate to driven delay
from ACLK
Note: All output times are measured with the specified load capacitance.
