INTRODUCTION
HIGHLIGHTS
DEVICE PROGRAMMER
The user memory for MCP250XX devices is initially blank when shipped from the
factory. The user must program the user memory with user-defined defaults. There are
three methods for programming the user memory.
1. Using MPLAB
2. Using the device programmer circuit on the MCP2515 with the programming
3. In-Circuit Serial Programming™ (ICSP™) while following the MCP250XX
The MCP250XX Development Kit supports two methods for programming the user
defaults.
1. Using the Device Programmer circuit with the programming software.
2. Node A has an ICSP connector.
A device programmer circuit is built into the board to allow the user to easily program
MCP250XX devices with the existing board (i.e., PRO MATE II is not needed).
4.3.1
The programming circuitry is designed to use the ICSP methodology as defined in the
MCP250XX Programming Specification (DS20072). The circuitry routes all of the
required signals, including the 13V V
regulator. Figure 4-1 shows the pinout for the MCP250XX socket in the device
programmer circuitry.
