Page Erase Operation
The Flash Memory must be first unlocked before implementing a page erase procedure. The
flash memory address is setup using the control registers, FMAR0, FMAR1 and FMAR2. The
Flash Memory Page Erase function is selected by the control bit, FMCR.2, in the FMCR register.
Setting the FMCR.7 bit high will start the Page Erase procedure. When the procedure has finished,
the MCU will continue to run automatically. The following flowchart illustrates the Page Erase
procedure.
