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 V
PP
= V
IL
, absolute hardware write protection is provided for all device blocks. If
V
PP
is at or below V
PPLK
, programming operations halt and SR3 is set, indicating a V
PP
-
level error. Block lock registers are not affected by the voltage level on V
PP
; they may still
be programmed and read, even if V
PP
is less than V
PPLK
.
