dsPIC30F Flash Programming Specification
5.6.3
PROGRAMMING VERIFICATION
Once the data EEPROM is programmed, the contents
of memory can be verified to ensure that the
programming was successful. Verification requires the
data EEPROM to be read back and compared against
the copy held in the programmer’s buffer. The READD
command reads back the programmed data EEPROM.
Alternatively, the programmer can perform the
verification once the entire device is programmed using
a checksum computation, as described in Section 6.8
“Checksum Computation”.
Note:
TBLRDL instructions executed within a
REPEAT loop must not be used to read
from Data EEPROM. Instead, it is
recommended to use PSV access.

Configuration Bits Programming
5.7.1
OVERVIEW
The dsPIC30F has Configuration bits stored in seven
16-bit registers. These bits can be set or cleared to
select various device configurations. There are two
types of Configuration bits: system-operation bits and
code-protect bits. The system-operation bits determine
the power-on settings for system-level components
such as the oscillator and Watchdog Timer. The code-
protect bits prevent program memory from being read
and written.
The FOSC Configuration register has three different
register descriptions, based on the device. The FOSC
Configuration
register
description
for
the
dsPIC30F2010 and dsPIC30F6010/6011/6012/6013/
6014 devices are shown in Table 5-4.
Note:
If user software performs an erase opera-
tion on the configuration fuse, it must be
followed by a write operation to this fuse
with the desired value, even if the desired
value is the same as the state of the
erased fuse.
The FOSC Configuration register description for the
dsPIC30F4011/4012 and dsPIC30F5011/5013 devices
is shown in Table 5-5.
The FOSC Configuration register description for
all remaining
devices
(dsPIC30F2011/2012,
dsPIC30F3010/3011/3012/3013,
dsPIC30F3014/
4013, dsPIC30F5015 and dsPIC30F6011A/6012A/
6013A/ 6014A) is shown in Table 5-6. Always use the
correct register descriptions for your target processor.
The FWDT, FBORPOR, FBS, FSS, FGS and FICD
Configuration registers are not device-dependent. The
register descriptions for these Configuration registers
are shown in Table 5-7.
The Device Configuration register maps are shown in
Table 5-8 through Table 5-11.
