The ____ is connected to the I-CODE and D-CODE bus
A
debugger
B
SRAM
C
program memory
D
peripheral
Explanation: 

Detailed explanation-1: -STM32 documentation says that the I-CODE and D-CODE buses are connected to the internal flash memory. The I-CODE bus is used to fetch instructions and the D-CODE bus is used for data access in the code memory region (literal load).

Detailed explanation-2: -The processor contains four bus interfaces: The ICode memory interface. Instruction fetches from Code memory space ( 0x0000000-0x1FFFFFFF) are performed over this 32-bit Advanced High-performance Bus (AHB)-Lite bus.

Detailed explanation-3: -The bus matrix module, BusMatrix, enables multiple AHB masters from different AHB buses to be connected to multiple AHB slaves on multiple AHB slave buses. It enables parallel access to a number of shared AHB slaves from a number of different AHB masters.
