Register bit 4 is set to '1' if there has been a pro-

gram failure.

Programming aborts if VPP drops out of the al-

lowed range or RP goes to VIL.

A Read Memory Array command must be issued

to return the memory to read mode before issuing

any other commands. Once the code has been

changed a device reset or power-down will make

the protection active with the new code.

See Appendix B, Figure 25, 26 and 27 for suggest-

ed flowcharts for using the Tuning Protection Pro-

gram command.
