GENERAL DESCRIPTION
These peripherals are supported by 8 sources 4-l evel interrupt capability. To facilitate programming an d verification, the Flash EPROM in side the W78E05 4D/W78E052D/W78E051D serie s allows the p rogram memory to be pro grammed and read electronically. Once the co de is confirmed, the user can protect the code for security. The W7 8E054D/W78E052D/W78E051D serie s micro controller has two powe r redu ction mod es, idle mode and power-down mode, both of which are software selectable. The idle mode turns off the processor clock but allows for continued peripheral operation. The power-down mode stops the crystal oscillator for mi nimum power consumption . The exter nal clock can b e stoppe d at any time and in any state witho ut affecting th e pro cessor. The W 78E054D/W78E052D/W78E051D se ries con tains InSystem Programmable (ISP) 2KB LDROM for loader program, operating voltage from 3.3V to 5.5V. Note: If the applied V DD is not stable , especially with long transiti...
