According to doc (http://www.auto-diagnostics.info/pdf/ford_eectch98.pdf), this 8061 microprocessor chip contains 256bytes of internal RAM (also referred to as register file in the doc). However, the only register file named in this diagram is a 120x16 register file(or 960bytes?) Hence, where is the 256bytes of internal RAM aka general purpose register And why is there a 120*16 register file instead? What is it made of?
Is the 256bytes of internal RAM in the instruction register? (which I assume Consists of the address and instruction register(among others as stated here https://cs.calvin.edu/activities/books/c++/engr-sci/WebItems/Chap05/ComputerArchitecture.pdf) ?
The Memory Map doesn’t show this as well.
