Complement clock of low power differenatial CPU clock pair. This clock will be free-running during iAMT.
True clock of low power differential CPU clock pair. This clock will be free-running during iAMT.
Ground Pin for CPU Outputs
Complement clock of low power differential CPU clock pair.
True clock of low power differential CPU clock pair.
Power Supply 3.3V nominal.
Notifies CK505 to sample latched inputs, or iAMT entry/exit, or PWRDWN# mode
Vih_FS values. TEST_MODE is a real time input to select between Hi-Z and REF/N divider mode while in
test mode. Refer to Test Clarification Table.
Ground pin for crystal oscillator circuit
Crystal output, nominally 14.318MHz.
Crystal input, Nominally 14.318MHz.
Power pin for the REF outputs, 3.3V nominal.
3.3V 14.318MHz reference clock/3.3V tolerant low threshold input for CPU frequency selection. Refer to
input electrical characteristics for Vil_FS and Vih_FS values/ TEST_SEL: 3-level latched input to enable
test mode. Refer to Test Clarification Table.
