2) Multiplicative override
In this mode, each output frequency is multiplied by an externally override frequency.
[Ex.1: VIA (Reference frequency), VIC (Override input)] [Ex.2: VIB (Reference frequency), VIA (Override input)]
Ex.1:
f660 = 0 (Disabled), f661 = 3 (VIC input), fmod = 1 (VIA input), fh = 8=0 , ul = 8=0
VIA input, (
f201 = 0
,
f202 = =0
,
f203 = 100
,
f204 = 8=0
)
VIC input (
f216 = 0
,
f220 = 0
,
f218 = 100
,
f221 = 100
)


Setting of VIA input: Refer to Section 7.3.1, Setting of VIC input: Refer to Section 7.3.2.
Output frequency = Reference frequency × {1 + Override (VIC input [%]/100)}
Ex.2:
f660 = 0
(Disabled),
f661 = 1
(VIA input),
fmod = 2
(VIB input),
fh = 8=0
,
ul = 8=0
VIB input (
f210 = 0
,
f211 = =0
,
f212 = 100
,
f213 = 8=0
)
VIA input ( f201 = 0 , f205 = 0 , f203 = 100 , f206 = 100 ) 

Setting of VIB input: Refer to Section 7.3.3, Setting of VIA input: Refer to Section 7.3.1.
Output frequency = Reference frequency × {1 + Override (VIA input [%]/100)}
