The SHI inputs are: MOSI/HA0, SS/HA2, MISO/SDA, SCK/SCL, and HREQ.
In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). PLL signals are
disabled during Stop state.
Periodically sampled and not 100% tested
Maximum values are derived using the methodology described in
application dependent and may vary widely from these numbers.
The timing waveforms in the AC Electrical Characteristics are tested with a V
maximum of 0.5 V and a V
MODA, MODB, MODC, and SHI pins (MOSI/HA0, SS/HA2, MISO/SDA, SCK/
SCL, HREQ). These pins are tested using the input levels set forth in the DC Electrical
Characteristics. AC timing specifications that are referenced to a device input signal
are measured in production with respect to the 50% point of the respective input
signal’s transition. DSP56004 output levels are measured with the production test
machine V
All output delays are given for a 50 pF load unless otherwise specified.
For load capacitance greater than 50 pF, the drive capability of the output pins
typically decreases linearly:
1. At 1.5 ns per 10 pF of additional capacitance at all output pins except MOSI/
2. At 1.0 ns per 10 pF of additional capacitance at output pins MOSI/HA0,
