PROGRAMMING VERIFICATION
After code memory is programmed, the contents of
memory can be verified to ensure that programming
was successful. Verification requires code memory to
be read back and compared against the copy held in
the programmer’s buffer.
The READP command can be used to read back all of
the programmed code memory.
Alternatively, you can have the programmer perform
the verification after the entire device is programmed
using a checksum computation.

Configuration Bits Programming
4.6.1
OVERVIEW
The PIC24FJXXXGA0XX family has Configuration bits
stored in the last two locations of implemented program
memory (see Table 2-2 for locations). These bits can
be set or cleared to select various device configura-
tions. There are three types of Configuration bits:
system operation bits, code-protect bits and unit ID bits.
The system operation bits determine the power-on
settings for system level components, such as
oscillator and Watchdog Timer. The code-protect bits
prevent program memory from being read and written.
The register descriptions for the CW1 and CW2
Configuration registers are shown in Table 4-2.

Bit Field
Register
Description
I2C1SEL(1)
CW2<2>
I2C1 Pin Mapping bit
1
= Default location for SCL1/SDA1 pins
0
= Alternate location for SCL1/SDA1 pins
DEBUG
CW1<11>
Background Debug Enable bit
1
= Device will reset in User mode
0
= Device will reset in Debug mode
FCKSM1:FCKSM0
CW2<7:6>
Clock Switching Mode bits
1x
= Clock switching is disabled, Fail-Safe Clock Monitor is disabled
01
= Clock switching is enabled, Fail-Safe Clock Monitor is disabled
00
= Clock switching is enabled, Fail-Safe Clock Monitor is enabled
FNOSC2:FNOSC0
CW2<10:8>
Initial Oscillator Source Selection bits
111
= Internal Fast RC (FRCDIV) oscillator with postscaler
110
= Reserved
101
