IMPORTANT: For this algorithm Secure contains an option ‘S’ to disable Serial Mode on the device.If enabled this option will program both the SPIEN bit to 1 and the RSTDISBL bit to 0.Since Serial Mode is used for Read/Compare/Verify these functions will fail (including ID check)if the device is Secured with the ‘S’ option. The SPIEN and RSTDISBL can no longer be programmedduring the normal Device Configure program phase and their option bits should be left at the default values.Buffer address range 0000h-7FFh is FLASH Program Memory and 800h-87Fh is EEPROM Data Memory.There are four Calibration Bytes residing in the signature row high byte ofaddresses 0000h 0001h 0002h and 0003h. They are for 1 2 4 and 8 MHz internal RC Oscillator calibrationrespectively. To program one of these four calibration bytes under Device Configure menu1)Set CALIBRATION to ENABLE2)Set CAL BYTE ADDRESS to one of the four Calibration Byte addresses (00h-03h).3)Set CALIBRATION ADDRESS to the memory address you want to program the Calibration Byte (from 0000h to 87Fh).New devices may automatically calibrate the RC Oscillator.Please set the CALIBRATION option to DISABLE(default) to use automatic calibration.
