AC measuring condition
Note1: The “n” in “Variable” means wait-number which is set to NDFMCR0<SPLW1:0>, and “m” means number which is
set to NDFMCR0<SPHW1:0>.
Example: If NDFMCR0<SPLW1:0> is set to “01”, n=1, t
RP
= (1.5 + n) T − 12 = 2.5T − 12
Note2: In above variable, the setting that result is minus can not use.
