SoC JTAG and Debug Interfaces
33.23.1
DC Specifications
contain the DC specifications for the JTAG and Debug signals.
These signals are in the 1.0-Volt SUS power well of the SoC.
• TCK (Input)
• TDI (Input)
• TMS (Input)
• TRST_B (Input)
• TDI (Input)
• TMS (Input)
• TRST_B (Input)
Notes:
1.
V
IH
is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
2.
V
IL
is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical low
value.
3.
Measured at V1P0A ÷ 2.
4.
Rwpu_40k and Rwpd_40k are only used for TRST_B.
Notes:
1.
Minimum V
OH
depends on the pull-down resistance on the system.
2.
Maximum V
OL
depends on the pull-up resistance on the system.
3.
Measured at V1P0A ÷ 2.
