/// @file exp_fw_log.H
/// @brief Helpers to access explorer firmware logs
/// The Explorer firmware modules log pertinent data regarding
/// operations and errors, and the Host manages and accesses this
/// information by using the EXP_FW_LOG API command. The firmware
/// maintains the log in a circular buffer in RAM and in the event
/// of a processor exception, firmware assert, or other critical
/// condition the firmware saves the data in RAM to SPI flash.
/// Having the log stored in non-volatile memory allows post-analysis
/// of the log even if it requires a power-cycle to recover the system.
