NOTES:
1. Input signals other than RESET# must be held constant in the Sleep state.
2. The BCLK can be stopped after DPSLP# is asserted. The BCLK must be turned on and within specification
before DPSLP# is deasserted.

Processor AC Timing Waveforms
The following figures are used in conjunction with the AC timing tables,
Table 18
through
Table
25
.
Note: For
Figure 9
through
Figure 24
, the following applies:
1.All common clock AC timings for AGTL+ signals are referenced to the Crossing Voltage
(V
CROSS
) of the BCLK[1:0] at rising edge of BCLK0. All common clock AGTL+ signal timings
are referenced at GTLREF at the processor core.
2.All source synchronous AC timings for AGTL+ signals are referenced to their associated strobe
(address or data) at GTLREF. Source synchronous data signals are referenced to the falling edge
of their associated data strobe. Source synchronous address signals are referenced to the rising
and falling edge of their associated address strobe. All source synchronous AGTL+ signal
timings are referenced at GTLREF at the processor core silicon.
3.All AC timings for AGTL+ strobe signals are referenced to BCLK[1:0] at V
CROSS
. All AGTL+
strobe signal timings are referenced at GTLREF at the processor core silicon.
4.All AC timings for the TAP signals are referenced to the TCK signal at 0.5*V
CC
at the processor
pins. All TAP signal timings (TMS, TDI, etc) are referenced at 0.5*V
CC
at the processor pins.
The circuit used to test the AC specifications is shown in
