If only RY/#BY is used for detecting programming status, the last page of the program sequence must
use the PAGE PROGRAM (10h) command instead of the CACHE PROGRAM (15h) command. If the
CACHE PROGRAM (15h) command is used every time, including the last page programming, Status
Register’s Bit 5 (I/O5) must be used to determine when programming is complete.
Status Register’s Pass/Fail, Bit 1 (I/O1) returns the pass/fail status for the previous page when Status
Register’s Bit 6 (I/O6) equals a “1” (ready state). The pass/fail status of the current PROGRAM
operation is returned with Status Register’s Bit 0 (I/O0) when Bit 5 (I/O5) of the Status Register equals
a “1” (ready state) as shown in Figure 9-15 and 9-16.
Note: The CACHE PROGRAM command cannot be used on blocks 0-3 if used as boot blocks.
