THE PROGRAMMING
EXECUTIVE
16.1
PE Communication
The programmer and the PE have a master-slave
relationship, where the programmer is the master
programming device and the PE is the slave.
All communication is initiated by the programmer in the
form of a command. The PE is able to receive only one
command at a time. Correspondingly, after receiving
and processing a command, the PE sends a single
response to the programmer.
16.1.1
2-WIRE ICSP EJTAG RATE
In Enhanced ICSP mode, the PIC32MX family devices
operate from the internal Fast RC oscillator, which has
a nominal frequency of 8 MHz. To ensure that the pro-
grammer does not clock too fast, it is recommended
that a 1 MHz clock be provided by the programmer.
16.1.2
COMMUNICATION OVERVIEW
The programmer and the PE communicate using the
EJTAG Address, Data and Fastdata registers. In partic-
ular, the programmer transfers the command and data
to the PE using the Fastdata register. The programmer
receives a response from the PE using the Address
and Data registers. The pseudo operation of receiving
a response is shown in the GetPEResponse pseudo
operation below:
Format:
response = GetPEResponse()
Purpose:
Enables the programmer to receive the 32-bit
response value from the PE.
EXAMPLE 16-1:
GetPEResponse
EXAMPLE
The typical communication sequence between the
programmer and the PE is shown in Table 16-1.
The sequence begins when the programmer sends the
command and optional additional data to the PE, and
the PE carries out the command.
When the PE has finished executing the command, it
sends the response back to the programmer.
The response may contain more than one response.
For example, if the programmer sent a READ
command, the response will contain the data read.
TABLE 16-1:
COMMUNICATION
SEQUENCE FOR THE PE
Note:
The Programming Executive (PE) is
located in the following folder within your
installation of MPLAB IDE:
...\Microchip\MPLAB IDE\REAL ICE
,
and then selecting the Hex PE file,
RIPE_06_xxxxxx
for PIC32MX3/4/5/6/7XX
or
RIPE_11_xxxxxx
for PIC32MX1/2XX.

do {
controlVal=XferData(32’h0x0004C000 );
} while( PrAcc(contorlVal<18>) is not ‘1’ );
// Select Data Register
SendCommand(ETAP_DATA);
// Receive Response
response = XferData(0);
// Tell CPU to execute instruction
SendCommand(ETAP_CONTROL);
XferData(32’h0x0000C000);
// return 32-bit response
return response;
