Microcomputer and memory access control method |
摘要 |
A microcomputer comprises a CPU, a built-in memory and a memory controller. The memory controller performs access control to the built-in memory in response to a memory access request from the CPU. The microcomputer further comprises a wait count register for storing a waiting period relating to memory access. The memory controller reads the waiting period upon receipt of the memory access request, and then, performs the access control to the built-in memory after a lapse of the waiting period. Low power consumption is achieved by utilizing the access control to the built-in memory without controlling a power source and an oscillator.
