Note: The Flash Embedded STEAK Algorithms
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).
Registers R5 to R15 are used internally by
STEAK, but preserved on entry and
restore on exit of STEAK.
IT IS VERY IMPORTANT TO TAKE INTO
ACCOUNT THE FACT THAT STEAK
USES UP TO 50 WORDS ON THE SYS-
TEM STACK. TO PREVENT ANY
ABNORMAL SITUATION, IT IS VERY
IMPORTANT TO INITIALIZE COR-
RECTLY THE STACK SIZE TO AT LEAST
64 WORDS, AND TO CORRECTLY INI-
TIALIZE REGISTER STKOV.
