Pin Name
JTAG 1149.1 requires a pull-up resistor on potentially undriven TDO/TMS signals.
If not using the RESET signal prior to CFGJTAG configuration, ensure that the V
when power-cycling the board. Failure to do this, could cause the Power-On-Reset (POR) circuitry to operate incorrectly.

Power-on-reset (POR) bypass input; used in
conjunction with POR_RESET to bypass the
internal POR circuit in favor of using an external
board-level POR circuit; the internal POR circuit is
bypassed when POR_BYPASS = 1; the
POR_BYPASS pin should be held at a static 0 or 1
while the System ACE CF controller is receiving
power.
Power-on-reset bypass input; can be used in
conjunction with POR_BYPASS to bypass the
internal POR circuit in favor of using an external
board-level POR circuit; all internal circuitry is reset
when POR_BYPASS = 1 and POR_RESET = 1;
The POR_RESET pulse duration should be at least
1 microsecond long.
Power-on-reset test output; this pin should be a true
No Connect on the board (see
but is listed here for informational purposes.
POR_TEST is Low during power up and when
POR_BYPASS and POR_RESET are asserted
High (causing a device reset). After power up is
complete, POR_TEST is High when POR_BYPASS
is Low, or when POR_BYPASS is High and
POR_RESET is Low. An internal timer circuit in the
POR component determines when to release
POR_TEST after power reaches the ON threshold.
