6.5
To allow portability of code, the programmer must read
the Configuration register locations from the hex file
(see
information is not present in the hex file, a simple
warning
programmer. Similarly, while saving a hex file, all
configuration information must be included. An option
can be provided not to include the configuration
information.
Microchip Technology Inc. feels strongly that this
feature is important for the benefit of the end customer.
6.6
Checksums for the dsPIC30F SMPS are 16 bits in size.
The checksum is calculated by summing the following:
• Contents of code memory locations
• Contents of Configuration registers

Item Description:
SUM(a:b) = Byte sum of locations a to b inclusive (all 3 bytes of code memory)
CFGB = Configuration Block (masked) = Byte sum of ((FBS&0x000F)+(FGS&0x0007)+(FOSCSEL&0x0003)+

Checksum Computation

the
All memory locations are summed one byte at a time,
using only their native data size. More specifically,
configuration and device ID registers are summed by
adding the lower two bytes of these locations (the
upper byte is ignored), while code memory is summed
by adding all three bytes of code memory.
Table 6-2
made for each dsPIC30F SMPS device. Computations
for read code protection are shown both enabled and
disabled. The checksum values assume that the
Configuration registers are also erased. However,
when code protection is enabled, the value of the FGS
register is assumed to be 0x0.
