JTAG data in
JTAG serial data in.
JTAG clock input
JTAG serial clock input.
JTAG data out
JTAG serial data out.
JTAG command
JTAG command signal, signals that the incoming serial data is command data.
Big Endian / Little Endian Control
Allows the system to change the processor addressing mode without rewriting
the mode ROM.
Vcc is OK
When asserted, this signal indicates to the ACT-7000ASC that the V
supply has been above the recommended value for more than 100 milliseconds
and will remain stable. The assertion of VccOK initiates the reading of the
boot-time mode control serial stream.
Cold Reset
This signal must be asserted for a power on reset or a cold reset. ColdReset
must be de-asserted synchronously with SysClock.
Reset
This signal must be asserted for any reset sequence. It may be asserted
synchronously or asynchronously for a cold reset, or synchronously to initiate a
warm reset. Reset must be de-asserted synchronously with SysClock.
Boot Mode Clock
Serial boot-mode data clock output at the system clock frequency divided by two
hundred and fifty six.
Boot Mode Data In
Serial boot-mode data input.
