PROGRAMMING EXECUTIVE
APPLICATION
3.1
Programming Executive Overview
The programming executive resides in executive
memory and is executed when Enhanced ICSP
Programming mode is entered. The programming exec-
utive provides the mechanism for the programmer (host
device) to program and verify the dsPIC30F, using a
simple command set and communication protocol.
The following capabilities are provided by the
programming executive:
Read memory
- Code memory and data EEPROM
- Configuration registers
-Device ID
Erase memory
- Bulk Erase by segment
- Code memory (by row)
- Data EEPROM (by row)
Program memory
- Code memory
- Data EEPROM
- Configuration registers
Query
- Blank Device
- Programming executive software version
The programming executive performs the low-level
tasks required for erasing and programming. This
allows the programmer to program the device by
issuing the appropriate commands and data.
The programming procedure is outlined in Section 5.0
3.2
Programming Executive Code
Memory
The programming executive is stored in executive code
memory and executes from this reserved region of
memory. It requires no resources from user code
memory or data EEPROM.
3.3
Programming Executive Data RAM
The programming executive uses the device’s data
RAM for variable storage and program execution. Once
the programming executive has run, no assumptions
should be made about the contents of data RAM.

CONFIRMING THE CONTENTS
OF EXECUTIVE MEMORY
Before programming can begin, the programmer must
confirm that the programming executive is stored in exec-
utive memory. The procedure for this task is illustrated in
First, ICSP mode is entered. The unique application ID
word stored in executive memory is then read. If the
programming executive is resident, the application ID
word is 0xBB, which means programming can resume
as normal. However, if the application ID word is not
0xBB,
the
programming
executive
must
be
programmed to Executive Code memory using the
Section 11.0 “ICSP Mode” describes the process
for the ICSP programming method. Section 11.13
procedure for reading the application ID word in ICSP
mode.
