0000 ; FLASH_CHECKSUM, PROTECT_BLOCK
0000 ; RETURNS:
0000 ; Nothing
0000 ;
0000 ; SIDE EFFECTS:
0000 ; The values of the A and X registers are modified
0000 ;
0000 ; PROCEDURE:
0000 ; 1) specify a 3 byte stack frame. Save in [KEYSP]
0000 ; 2) insert the flash Supervisory key in [KEY1]
0000 ; 3) store function code in A

0000 ;
0000 ; These definitions are used to describe RAM access patterns. They provide
0000 ; documentation and they control prologue and epilogue macros that perform
0000 ; the necessary housekeeping functions for large memory model devices like
0000 ; the CY8C27x66 and CY8C29x66.

0000 ; ******* Page Pointer Manipulation Macros *******
0000 ;
