Chip Identifier (CHIPID)

Purpose

Driver for the Chip Identifier. This driver provides access to the main features of the CHIPID.

Usage

1. Read whole Chip ID information to a struct using chipid_read(). The read data is defined using chipid_data_t.
2. Read Chip ID fields using following functions:
   • Device version: chipid_read_version();
   • Embedded processor: chipid_read_processor();
   • Non volatile program memory size: chipid_read_sramsize();
   • Second non volatile program memory size: chipid_read_nvpm2size();
   • Internal SRAM size: chipid_read_sramsize();
   • Architecture Identifier: chipid_read_arch();
   • Non volatile program memory type: chipid_read_nvpmtype();
   • Extension flag: chipid_read_extchipid().

Dependencies

This driver does not depend on other modules.
