5.7.1.4. March C- SRAM Test
A structural SRAM test is started by using command 17. During memory test data register SRD0 is
read back as 1. When the test is finished SRD0 indicates the test result, 0 for pass, and 2 for fail.
5.7.1.5. EEPROM Calibration and User Data Space
Located at the bottom of the EEPROM there is a file system storing calibration data regarding the
ADC, RC oscillator and others, along with DMCE and PFC firmware. Calibration data include the
FLL divider, as well as the ADC offset and gain values. After power-on reset the EEPROM's
content is copied to the Shadow SRAM, this includes the calibration and user data space.
