dsPIC30F Flash Programming Specification
11.13 Reading the Application ID Word
The application ID word is stored at address 0x8005BE
in executive code memory. To read this memory
location, you must use the SIX control code to move
this program memory location to the VISI register. The
REGOUT control code must then be used to clock the
contents of the VISI register out of the device. The
corresponding control and instruction codes that must
be serially transmitted to the device to perform this
operation are shown in Table 11-13.
Once the programmer has clocked-out the application
ID word, it must be inspected. If the application ID has
the value 0xBB, the programming executive is resident
in memory and the device can be programmed using
the mechanism described in Section 5.0 “Device
Programming”. However, if the application ID has any
other value, the programming executive is not resident
in memory. It must be loaded to memory before the
device can be programmed. The procedure for loading
the programming executive to the memory is described
11.14 Exiting ICSP Mode
After confirming that the programming executive is
resident in memory, or loading the programming
executive, ICSP mode is exited by removing power to
the device or bringing MCLR to VIL. Programming can
then take place by following the procedure outlined in
