Program Operations
Program Resume
The RESUME command instructs the device to continue programming, and automati-
cally clears SR[7,2]. This command can be written to any address. If error bits are set,
the status register should be cleared before issuing the next command. RST# must re-
main de-asserted.
Program Protection
When VPP = VIL, absolute hardware write protection is provided for all device blocks. If
VPP is at or below VPPLK, programming operations halt and SR3 is set, indicating a VPP
level error. Block lock registers are not affected by the voltage level on VPP; they may still
be programmed and read, even if VPP is less than VPPLK
