Project Info

78K0/KE2 is interesting uC family because code can be executed from internal expanded RAM (4 KB). But very probably UC-214 is protected from erasing because it is typical in car radios...
Memory is organised as 32KB common area + 4 banks of 16KB what is not very convienent but probably can be used for a storage of users applications.
