/*
* `lf_tharexde` simulates EM4x50 dumps uploaded words/blocks, reads words of standard read
* mode of EM4x50 tags and stores them in internal flash.
* `lf_tharexde` simulates EM4x50 dumps uploaded to flash, reads words
* transmitted by EM4x50 tags in standard read mode and stores them in
* internal flash.
* It requires RDV4 hardware (for flash and battery).
*
* On entering stand-alone mode, this module will start simulating EM4x50 data.
* Data is read from eml dump file uploaded to flash memory.
*
* On switching to read/record mode by pressing pm3 button, module will start
* reading/recording EM4x50 data. Every found / collected data will be
* written/appended to the logfile in flash as a text string.
* reading EM4x50 data. Each collected data set will be written/appended to the
* logfile in flash as a text string.
*
* LEDs:
* - LED A: simulating
* - LED B: reading / record
* - LED B: reading/recording
* - LED C: writing to flash
* - LED D: unmounting/sync'ing flash (normally < 100ms)
