5) Automatic erasing of protection bits
Different results will be obtained when the automatic protection bit erase command is
executed depending on the status of the protection bits and the security bits. It depends on
the status of FLCS <BLPRO> whether all the <BLPRO> bits are set to "1" or not if
SECBIT<SECBIT> is 0x1. Be sure to check the value of FLCS <BLPRO> before executing
the automatic protection bit erase command. See chapter 17 for details.
・ When all the FLCS <BLPRO> bits are set to "1" (all the protection bits are
programmed):
・ When the FLCS <BLPRO> bits include "0" (not all the protection bits are
programmed):
The protection condition can be canceled by the automatic protection bit erase operation.
With this device, protection bits set by an individual block can be erased handling all the
blocks at a time as shown in Table 18-21. The target bits are specified in the seventh bus
write cycle and when the command is completed, the device is in a condition all the blocks
are erased. The protection status of each block can be checked by FLCS <BLPRO> to be
described later. This status of the programming operation for automatic protection bits can
be checked by monitoring FLCS <RDY/BSY>. When the automatic operation to erase
protection bits is normally terminated, the protection bits of FLCS <BLPRO> selected for
erasure are set to "0."
In any case, any new command sequence is not accepted while it is in an automatic
operation to erase protection bits. If it is desired to stop the operation, use the hardware
reset function. When the automatic operation to erase protection bits is normally terminated,
it returns to the read mode.
When the automatic protection bit erase command is command written, the flash memory is
automatically initialized within the device. When the seventh bus write cycle is completed,
the entire area of the flash memory data cells is erased and then the protection bits are
erased. This operation can be checked by monitoring FLCS <RDY/BSY>. If the automatic
operation to erase protection bits is normally terminated, FLCS will be set to "0x00000001."
While no automatic verify operation is performed internally to the device, be sure to read the
data to confirm that it has been correctly erased. For returning to the read mode while the
automatic operation after the seventh bus cycle is in progress, it is necessary to use the
hardware reset to reset the device. If this is done, it is necessary to check the status of
protection bits by FLCS <BLPRO> after retuning to the read mode and perform either the
automatic protection bit erase, automatic chip erase, or automatic block erase operation, as
appropriate.
(Note)
(Note) The FLCS <RDY/BSY> bit is "0" while in automatic operation and it
turns to "1" when the automatic operation is terminated.
The TMPM330FYFG is configured with block 2 through 5. Block 0 and 1
require a programming of protection bits when using security function.
