Read Data History From SPI Flash Memory
This command copies the Data History from the SPI ROM into the SRAM. After power is supplied, or RESET
asserted the SRAM Data History log information is no longer available. Running this command permits the history
to be restored from the non-volatile SPI ROM.
To read data history from the SPI ROM into SRAM:
1. From the terminal window press 5. The transaction log is listed.
Write Data to SRAM (Specified Address and Data)
This command allows you to write a single data value to any location in the SRAM memory space.
1. From the terminal window press 6.
Read Data from SRAM (Specified Address)
This command allows you to read the data value from any address in the SRAM.
1. From the terminal window press 7.
Write Data to SPI (Specified Address and Data)
This command allows you to write a single data value to any location in the SPI memory space.
1. From the terminal window press 8.
