Electrical Specifications
.
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 17 through
NOTES:
1. All common clock AC timings for AGTL+ signals are referenced to the Crossing Voltage (VCROSS) 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 VCROSS. 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*VCC at the processor pins. All TAP
signal timings (TMS, TDI, etc) are referenced at 0.5*VCC at the processor pins.
