(0009) ; DESCRIPTION:
(0010) ; M8C Boot Code for CY7C63800 microcontroller family.
(0011) ; This file also contains the Interrupt Service Routines for enCoRe II GPIO
(0012) ; interrupts: INT0, INT1, INT2, as well as the GPIO Port interrupts for
(0013) ; port 0, port 1, port 2, and port 3.

(0017) ; NOTES:
(0018) ; PSoC Designer's Device Editor uses a template file, BOOT.TPL, located in
(0019) ; the project's root directory to create BOOT.ASM. Any changes made to
(0020) ; BOOT.ASM will be overwritten every time the project is generated; therfore
(0021) ; changes should be made to BOOT.TPL not BOOT.ASM. Care must be taken when
(0022) ; modifying BOOT.TPL so that replacement strings (such as @PROJECT_NAME)
(0023) ; are not accidentally modified.
