Register bit 4 is set to '1' if there has been a pro-
gram failure.
Programming aborts if V
PP
drops out of the al-
lowed range or RP goes to V
IL
.
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.
Table 9. Commands
Note: 1. X Don’t Care; RA Read Address, RD Read Data, ID Device Code, SRD Status Register Data, PA Program Address; PD Program
Data, QA Query Address, QD Query Data, BA Any address in the Block, BCR Burst Configuration Register value, TPA = Tuning
Protection Address, TPC = Tuning Protection Code.
2. Cycles 1 and 2 input the first 32 bits of the code, cycles 3 and 4 the second 32 bits of the code.
