Standard 8051 8-Bit Flash MCU
HT85F2260/HT85F2270/HT85F2280
Byte Read Operation
The Flash memory must be first unlocked before implementing a byte read procedure. The flash
memory address is setup using the control registers, FMAR0, FMAR1 and FMAR2. The Flash
Memory Page Read function is selected by the control bit, FMCR.1, in the FMCR register. When
the FMCR.7 bit is set high the Byte Read procedure will be initiated. When the procedure is ready,
the MCU will continue to run automatically. The following flowchart illustrates the Byte Read
procedure.
