– If a Reset Flash instruction is received, data in
the Flash memory sector that was being erased
is invalid.
Resume Sector Erase.
If
Erase instruction was previously executed, the
erase cycle may be resumed with this instruction.
The Resume Sector Erase instruction consists of
writing 030h to any address while an appropriate
Sector Select(FS0-FS7 or CSBOOT0-CSBOOT3)
is High. (See Table 85.)
Specific Features
Flash Memory Sector Protect.
Each
and secondary Flash memory sector can be sepa-
rately protected against Program and Erase cy-
cles. Sector Protection provides additional data
security because it disables all Program or Erase
cycles. This mode can be activated through the
JTAG Port or a Device Programmer.

primary
Sector protection can be selected for each sector
using the PSDsoft Express Configuration pro-
gram. This automatically protects selected sectors
when the device is programmed through theJTAG
Port or a Device Programmer. Flash memory sec-
tors can be unprotected to allow updating of their
contents using the JTAG Port or a Device Pro-
grammer. The MCU can read (but cannot change)
the sector protection bits.
Any attempt to program or erase a protected Flash
memory sector is ignoredby thedevice. TheVerify
operation results in a READ of the protecteddata.
This allows aguarantee of the retention of the Pro-
tection status.
The sector protection status can be read by the
MCU through the Flash memory protection regis-
ters (in the CSIOPblock). See Table 87 and Table
88.
