Question
I have read the question and use the HCS12 Microcontrollers and Embedded Systems, 1st Edition to pick D for both of them. I am having problems where I not sure if I have chosen the right answer. I need help with these two problems, and it is due today? Thank you
What is a microcontroller's machine language?
A. A language used by machines talking to each other
B. A controller’s entire instructions in binary form
C. A language used by operators talking to machines
D. A controller’s entire mnemonic forms
HCS12’s I/O register space is
A. A place to register HCS12 product
B. A memory space to host all I/O related registers
C. A place to put all registers
D. A memory block to host all HCS12’s CPU registers
Explanation / Answer
What is a microcontroller's machine language?
A controller’s entire instructions in binary form
Assemby language is converted to 0's and 1's form to make the controller understand.
HCS12’s I/O register space is
A memory space to host all I/O related registers
I/O devices share the same memory space and have their own separate I/O memory space. Currently trend is to use “memory mapped I/O” by using the same address space for memory and I/O devices.
