Notes
Retrieves PPPP count UFM pages. Only the
least significant 14 bits of PP PP are used
for the page count.
The 'M' field must be set based on the con-
figuration port being used to read the UFM.

Exit Offline or Transparent programming
mode. ISC_DISABLE causes the MachXO2
to automatically reconfigure when leaving
Offline programming mode. Thus, when
leaving Offline programming mode the Con-
figuration SRAM must be explicitly cleared
using ISC_ERASE (0x0E) prior to transmit-
ting ISC_DISABLE. The recommended exit
command from Offline programming mode
is LSC_REFRESH (0x79), wherein
ISC_ERASE and ISC_DISABLE are not
necessary. See Figure 20.
No Operation and Device Wakeup
Force the MachXO2 to reconfigure. Trans-
mitting a REFRESH command reconfigures
the MachXO2 in the same fashion as
asserting PROGRAMN.
Program the Security bit (Secures CFG
2
Flash sector).
Program the Security Plus bit (Secures CFG
2
and UFM Sectors).
