MULTSEL_Override
This bit control the selection of IREF multiple.
0 = HW control; IREF multiplier is determined by MULTSEL[0:1] input pins
1 = SW control; IREF multiplier is determined by Byte[4], Bit[5:6].
IREF multiplier
00 = Ioh is 4 x IREF
01 = Ioh is 5 x IREF
10 = Ioh is 6 x IREF
11 = Ioh is 7 x IREF

FS_Override
Latched FS[4:0] inputs. These bits are read only.
0 = Select operating frequency by FS[4:0] input pins
1 = Select operating frequency by SEL[4:0] settings
0 = 48-MHz output on pin 27, 1 = 66-MHz output on pin 27
0 = 24-MHz,1 = 48-MHz
