ispPAC-POWR1220AT8 Data Sheet

UES_PROGRAM – This instruction will program the content of the UES Register into the UES E
CMOS memory.
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-POWR1220AT8 sequence
from starting.
PROGRAM_DONE_BIT – This instruction sets the 'Done' bit, which enables the ispPAC-POWR1220AT8
sequence to start.
RESET – This instruction resets the PLD sequence and output macrocells.
IN1_RESET_JTAG_BIT – This instruction clears the JTAG Register logic input 'IN1.' The PLD input has to be con-
figured to take input from the JTAG Register in order for this command to have effect on the sequence.
IN1_SET_JTAG_BIT – This instruction sets the JTAG Register logic input 'IN1.' The PLD input has to be config-
ured to take input from the JTAG Register in order for this command to have effect on the sequence.
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 output
pins, in which the open-drains are tri-stated and the FET drivers are pulled low.

Before any of the above programming instructions are executed, the respective E
CMOS bits need to be erased
using the corresponding erase instruction.
