VDD_CPU
PWR
3.3V Power supply for CPU PLL.
63
CKPWRGD/PD#
I
3.3V LVTTL input. This pin is a level sensitive strobe used to latch the FS_A, FS_B,
FS_C, FS_D, SRC5_SEL, and ITP_EN.
After CKPWRGD (active HIGH) assertion, this pin becomes a real-time input for
asserting power down (active LOW).
64
FSB/TEST_MODE
I
3.3V tolerant input for CPU frequency selection.
Selects Ref/N or Tri-state when in test mode
0 = Tri-state, 1 = Ref/N.
Refer to DC Electrical Specifications table for Vil_FS and Vih_FS specifications.
