The configuration of the WriteBlock function is straightforward.
The BLOCKID of the Flash block, where the data is stored,
must be determined and stored at SRAM address FAh.
The SRAM address of the first of the 64 bytes to be stored in
Flash must be indicated using the POINTER variable in the
parameter block (SRAM address FBh). Finally, the CLOCK
and DELAY value must be set correctly. The CLOCK value
determines the length of the write pulse that will be used to
store the data in the Flash. The CLOCK and DELAY values are
dependent on the CPU speed and must be set correctly. Refer
to “Clocking” Section for additional information.
EraseBlock Function
The EraseBlock function is used to erase a block of 64
contiguous bytes in Flash. The first thing the EraseBlock
function does is to check the protection bits and determine if
the desired BLOCKID is writable. If write protection is turned
on, the EraseBlock function will exit setting the accumulator
and KEY2 back to 00h. KEY1 will have a value of 01h,
indicating a write failure. The EraseBlock function is only
useful as the first step in programming. Erasing a block will not
cause data in a block to be one hundred percent unreadable.
If the objective is to obliterate data in a block, the best method
is to perform an EraseBlock followed by a WriteBlock of all
zeros.
To set up the parameter block for the EraseBlock function,
correct key values must be stored in KEY1 and KEY2. The
block number to be erased must be stored in the BLOCKID
variable and the CLOCK and DELAY values must be set based
on the current CPU speed.
ProtectBlock Function
The enCoRe II LV devices offer Flash protection on a block-
by-block basis.
Table 26
lists the protection modes available.
In the table, ER and EW are used to indicate the ability to
perform external reads and writes. For internal writes, IW is
used. Internal reading is always permitted by way of the
ROMX instruction. The ability to read by way of the SROM
ReadBlock function is indicated by SR. The protection level is
stored in two bits according to
Table 26
. These bits are bit
packed into the 64 bytes of the protection block. Therefore,
each protection block byte stores the protection level for four
Flash blocks. The bits are packed into a byte, with the lowest
numbered block’s protection level stored in the lowest
numbered bits
Table 26
.
The first address of the protection block contains the
protection level for blocks 0 through 3; the second address is
for blocks 4 through 7. The 64th byte will store the protection
level for blocks 252 through 255.
The level of protection is only decreased by an EraseAll, which
places zeros in all locations of the protection block. To set the
level of protection, the ProtectBlock function is used. This
function takes data from SRAM, starting at address 80h, and
ORs it with the current values in the protection block. The
result of the OR operation is then stored in the protection
block. The EraseBlock function does not change the
protection level for a block. Because the SRAM location for the
protection data is fixed and there is only one protection block
per Flash macro, the ProtectBlock function expects very few
variables in the parameter block to be set prior to calling the
function. The parameter block values that must be set, besides
the keys, are the CLOCK and DELAY values.
