What is bhe in microprocessor?

Answer 1

BHE, or Byte High Enable, is a control signal used in microprocessors to indicate whether the high byte (the upper 8 bits) of a data word is being accessed during a read or write operation. In a typical 16-bit data bus, BHE helps manage which byte of data is being transmitted, allowing for efficient memory access and data manipulation. This is particularly important in systems that handle both 8-bit and 16-bit data, enabling the processor to work with data of varying sizes without ambiguity.
