The Byte-Verify command allows the user to verify that the
SST89C54/58 has correctly performed an Erase or Pro-
gram command. Byte-Verify command returns the data
byte in SFDT. The user is required to check that the previ-
ous Flash operation has fully completed before issuing a
Byte-Verify. Byte-Verify command execution time is short
enough that there is no need to poll for command comple-
tion and no interrupt is generated. The Byte-Verify com-
mand sequence is as follows:
Prog-SB3, Prog-SB2, Prog-SB1 commands are used to
program the Security bits (see Table 8-1). Upon completion
of any of those commands, the security options will be
updated immediately.
Security bits previously in un-programmed state can be
programmed by these commands. The Prog-SB3, Prog-
SB2, Prog-SB1 sequences are as follows:
Prog-RB1, Prog-RB0 commands are used to program the
RE-MAP[1:0] bits (see Table 3-1). These commands only
change the RE-MAP[1:0] bits and have no effect on Map-
En[1:0] until after a reset cycle. Therefore, the effect of
these commands is not immediate.
Re-Map bits previously in un-programmed state can be
programmed by these commands. The Prog-RB1, Prog-
RB0 sequences are as follows:
Prog-SB3, Prog-SB2, Prog-SB1, Prog-RB1, and Prog-RB0
commands must reside only in Block 0 (32 KByte block) or
external code memory.
Any such instructions issued from Block 1 may cause
unpredictable program behavior.
4.2.4 Polling
A command that uses the polling method to detect flash
operation completion should poll on the Flash_busy bit
(SFST[2]). When Flash_busy de-asserts (logic 0), the
device is ready for the next operation.
The BUSY bit (SFST[3]) is provided for Burst-Program. In
between bytes within a burst sequence, the Busy bit will
become logic 0 to indicate that the next Burst-Program byte
should be presented. Completion of the full burst cycle is
indicated also by Flash_busy bit (SFST[2]).
MOVC instruction may also be used for verification of the
Programming and Erase operation of the flash memory.
MOVC instruction will fail if it is directed at a flash block that
is still busy.
