EPTR=formula
EEPROM Pointer
APPLICATION: EEPROM (Nonvolatile Memory)
DESCRIPTION: Set user data EEPROM pointer
EXECUTION: Immediate
CONDITIONAL TO: N/A
LIMITATIONS: N/A
READ/REPORT: REPTR
WRITE: Read/write EPTR auto incremented as used
LANGUAGE ACCESS: Assignment, formulas and conditional testing
UNITS: EEPROM address pointer (bytes)
RANGE OF VALUES: 0 to 32767
TYPICAL VALUES: 0 to 32767
DEFAULT VALUE: 0
FIRMWARE VERSION: 5.x and later
COMBITRONIC: N/A
DETAILED DESCRIPTION:
EPTR sets the address location (pointer) within the nonvolatile, user-data EEPROM for the
data-retrieval read VLD(variable, number) function, and data-storage write VST(variable,
number) function. EPTR auto-increments by 1, 2 or 4 with each read or write access to the
physical EEPROM device according to the current data type.
EXAMPLE:
EPTR=4000'Set EPTR = 4000
VST(hh,1) 'Store a 32-bit value; EPTR is now 4004
VST(ab[7],1) 'Store an 8-bit value; EPTR is now 4005
VST(aw[7],1) 'Store a 16-bit value; EPTR is now 4007
VST(x,3) 'Store three consecutive variables: x, y, z
'EPTR is now 4007+(3*4) or 4019
VST(x,4) 'INVALID !!! EPTR remains 4019 !!!
NOTE: You cannot store consecutive variables past their group range (i.e.,
consecutive variables a-z, aa-zz or aaa-zzz must be stored within their groups).
VST(aa,26)'Perfectly valid !!!
VST(aa,27) 'INVALID !!!
