Embodiment Construction
[0014] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0015] It should be noted that, the embodiment of the present invention takes the 8051 single-chip microcomputer as an example, but it is not limited to the 8051 single-chip microcomputer, and can be any applicable MCU.
[0016] The existing 8051 single-chip microcomputer has a 4KB program storage unit, and its address is 0000H-0FFFH. Among them, the address units from 80H-FFH (also 128 bytes) are SFR units, and the internal data storage area stores up to 128 SFRs. The 21 SFRs available in the 8051 MCU are discontinuously distributed in 128-byte SFR units, and users of SFRs in other vacant addresses cannot read and write.
[0017] In order to expand the vacant address in the SFR unit in the existing 8051 microcontroller, the application proposes figure 1 An SoC system is shown, which includes: a m...
