Lattice Semiconductor
IDCODE – This instruction connects the output of the Identification Code Data Shift (IDCODE) Register to TDO
(Figure 4-20), to support reading out the identification code.
Figure 4-20. IDCODE Register
PROGRAM_DISABLE – This instruction disables the programming mode of the ispPAC-POWR607. The Test-
Logic-Reset JTAG state can also be used to cancel the programming mode of the ispPAC-POWR607.
UES_READ – This instruction both reads the E
between the TDI and TDO pins (as shown in Figure 4-17), to support programming or reading of the user electronic
signature bits.
Figure 4-21. UES Register
UES_PROGRAM – This instruction will program the content of the UES Register into the UES E
The device must already be in programming mode (PROGRAM_ENABLE instruction). This instruction also forces
the outputs into the OUTPUTS_HIGHZ.
ERASE_DONE_BIT – This instruction clears the ‘Done’ bit, which prevents the ispPAC-POWR607 sequence from
starting.
PROGRAM_DONE_BIT – This instruction sets the ‘Done’ bit, which enables the ispPAC-POWR607 sequence to
start.
RESET – This instruction resets the PLD sequence and output macrocells. The condition of the ispPAC-POWR607
is the same as initial turn-on after POR is completed.
PLD_VERIFY_INCR – This instruction reads out the PLD data register for the current address and increments the
address register for the next read.
Notes:
In all of the descriptions above, OUTPUTS_HIGHZ refers both to the instruction and the state of the digital and
FET driver output pins, in which all are tri-stated.
Before any of the above programming instructions are executed, the respective E
using the corresponding erase instruction.
