require at least 50 words on the Internal
System Stack for proper operation. The
program itself verifies that there is enough
free space on the System Stack before
performing a programming or erasing
operation, by computing the Word number
between Stack Pointer (SP) and Stack
Overflow register (STKOV ).
The MDH, MDL and MDC register content
are modified.
Registers R0 to R4 are used as Input Data
for STEAK, and are modified as explained
above (Return Values).

Operation was successful
Flash Protection is active
Vpp voltage not present
Programming operation failed
Address value (R1) incorrect: not in Flash address area or odd
CPU period out of range (must be between 30 ns to 500 ns)
Not enough free space on system stack for proper operation
Incorrect bank number (R2,R3) specified
Erase operation failed (phase 1)
Bad source address for Multiple Word programming command
Bad number of words to be copied in Multiple Word programming command: one destination will be
out of flash.
PLL Unlocked or Oscillator watchdog overflow occured during programming or erasing the flash.
Erase operation failed (phase 2)
Unknown or bad command
