Recommended
Calibration Flow
Following flow is recommended to calibrate the 2K byte Flash EEPROM
array area. It is assumed that this flow is executed after reset without
initialization of the registers INITCRM and CALCFG.
1. Copy a 2K byte block of data from the Flash EEPROM into the 2K
byte CALRAM array. Figure 33 shows an example. This is the first
step for calibration, but this step may be skipped when
initialization for calibration block is not needed.
The data to be calibrated in Flash EEPROM has to be located within the
2K byte area which is overlapped by the CALRAM.
