Pullup/Pulldown and Unused Pin Guidelines
For normal (i.e., non-test mode) operation, terminate signals as follows:
Terminate unused signals as follows:
For shared IX Bus operation, it is recommended to pullup PORTCTL_L[3:0] and, additionally,
FPS[2:0] and TXASIS at the designer’s discretion.
Typical pullup/pulldown resistor values are in the range of 5-10 KOhms.

Function
Pullup these signals to VDDX: TMS, TDI.
TCK may be pulled up to VDDX or pulled down to VSSX at the system designer’s option.
Pulldown these signals to VSS: SCAN_EN, TCK_BYP, TRST_L.
Pullup this signal to VDDX or pulldown to VSS; do not allow it to float: TSTCLK.
GPIO[3:1] and GPIO[0] are tri-stated during reset. If these signals are used to drive external
logic, pullup or pulldown as approprate to ensure valid logic levels during reset.
Pullup these signals to VDDX: GNT_L[1], TK_IN, EOP32.
Pulldown these signals to VSS: NA/SACLK, FAST_RX1, FAST_RX2.
