Token: 0xE1
The EDBG has 10 pins designated for extension board identification. These pins are sampled on power-up and the extension board identification information is stored. This information can be retrieved by using the Extension Boards token.
The first part of the response from this request is a 2-byte BE (1st byte is MSB) extension map containing information of which extension slots are populated. A '1' in bit 0 of the extension map means that EXT1 is populated, a '0' means not populated. If there are extension modules present the 64-byte content of each of the ID chips is sent. It will start with EXT1. If the extension is present it will send the content, otherwise no data is sent.
