3.3V-1.05V power supply for SRC outputs.
38
SRC8#/CPUC2_ITP#
O, DIF Selectable differential CPU or SRC clock output. ITP_EN = 0 @ CK_PWRGD
assertion = SRC8
ITP_EN = 1 @ CK_PWRGD assertion = CPU2
Note: CPU2 is an iAMT clock in iAMT mode depending on the configuration set in Byte 11
Bit3:2.
39
SRC8/CPUT2_ITP
O, DIF Selectable differential CPU or SRC clock output. ITP_EN = 0 @ CK_PWRGD
assertion = SRC8
ITP_EN = 1 @ CK_PWRGD assertion = CPU2
Note: CPU2 is an iAMT clock in iAMT mode depending on the configuration set in Byte 11
Bit3:2.
40
SEL_24.576M
I, PD
Select 25M1_24.576M output and SRC1
0 = 25M1, M= SRC1, 1 = 24.576M
41
