ispClock5600 Family Data Sheet
2
VERIFY – This instruction loads data from the E
CMOS array into the column register. The data may then be
shifted out. The device must already be in programming mode for this instruction to execute.
2
VERIFY_INCR – This instruction copies the E
CMOS column pointed to by the address register into the data col-
umn register and then auto-increments the value of the address register. The device must already be in program-
ming mode for this instruction to execute.
DISCHARGE – This instruction is used to discharge the internal programming supply voltage after an erase or pro-
gramming cycle and prepares ispClock5600 for a read cycle.
2
PROGRAM_USERCODE – This instruction writes the contents of the UES register (32 bits) into E
CMOS memory.
The device must already be in programming mode for this instruction to execute.
2
USERCODE – This instruction both reads the UES string (32 bits) from E
CMOS memory into the UES register
and addresses the UES register so that this data may be shifted in and out.
HIGHZ – This instruction forces all outputs into a High-Z state.
CLAMP – This instruction drives I/O pins with the contents of the boundary scan register.
USER_LOGIC_RESET – This instruction resets all user-accessible logic, similar to asserting a HIGH on the
RESET pin.
INTEST – This instruction performs in-circuit functional testing of the device.
ERASE_DONE – This instruction erases the ‘DONE’ bit only. This instruction is used to disable normal operation of
the device while in programming mode until a valid configuration pattern has been programmed.
PROGRAM_DONE – This instruction programs the ‘DONE’ bit only. This instruction is used to enable normal
device operation after programming is complete.
NOOP – This instruction behaves similarly to the CLAMP instruction.
