Hello Everyone=20
Anybody know or can help me to find out more information regarding the init=
ialization value of SRAM contents during power up .=20
I would like to save some values in sram so that I can read that back after=
a reset , for eg=A0 saving a byte value and its compliment=A0 and check th=
e consistency between these two variables . This would make sure that, the =
value is really what I saved prior to reset and not the garbage value which=
would appear in the memory after a power up.=20
Any existing behavior known for mpc microcontrollers related to this?=20
if it is stored like the value and its compliment , what=A0 is the probabil=
ity of the random initial values in two bytes to be=A0compliment of each ot=
her=A0 and mistaken as the good value =A0=A0=A0
Regards
