• Sector Address Table

•Registers

FLCR : Status register (CPU mode)

This register indicates the FLASH memory operating status. The register controls interrupts to the CPU as well

as writing to the FLASH memory.

This register is accessible only in CPU mode. Do not access this register with read modify write instructions.

FWTC : Wait register

This register controls waiting for the FLASH memory in CPU mode.

The register also controls accessing to read from the FLASH memory (33 MHz operations) at high speeds.
