MPC8245 Integrated Processor Hardware Specifications, Rev. 10

Freescale Semiconductor

Electrical and Thermal Characteristics

Figure 20 through Figure 23 show the different timing diagrams.

TMS, TDI data hold time

—

TCK to TDO data valid

TCK to TDO high impedance

Notes:

1. TRST is an asynchronous signal. The setup time is for test purposes only.

2. Nontest (other than TDI and TMS) signal input timing with respect to TCK.

3. Nontest (other than TDO) signal output timing with respect to TCK.
