MC9S08DZ60A - Big endian

Sangram — Thu, 26 Jul 2007 19:57:43 GMT

Hello ,

I am using MC9S08DZ60A uc. I want to know is it little endian or big endian.

I know that by writting C prgram we can check it. But, right now I dont have compiler.

So, help is greatly appreciated.

Regards

Sangram

In the 9S08 Reference Manual, even though it isn't explicitly mentioned, it is implied by the word sized register definitions (MSB in lower address, LSB in higher address), and also in the various CPU instruction details. For example, the byte order of the push of the PC register on the stack during a JSR.

Hello,

There are Two main format in the world.
Motorola which is now Freescale one.
Intel which is the opposite from Freescale.

Google is my friend:
