Peripheral Simulation

For Silicon Laboratories, Inc. C8051F320 — Flash Memory

Simulation support for this peripheral or feature is comprised of:

• Dialog boxes which display and allow you to change peripheral configuration.

These simulation capabilities are described below.

Flash Memory Dialog

The Flash Memory dialog displays and configures simulation capabilities of the on-chip Flash memory.

Flash Memory

• FLACL (Flash Access Limit) contains the MSB of the 16-bit program memory read/write/erase limit address.
• FLSCL (Flash Memory Control) contains the one-shot timer enable (FOSE), the read always enable (FRAE) and the read write enable settings.
• FLWE (FLASH Read/Write Enable) is set to enable writing to Flash.
• PSCTL (Program Store Read/Write Control) contains the following settings:
• SFLE (Scratchpad FLASH Memory Access Enable) is set to direct FLASH reads and writes from user software to the 128-byte Scratch-pad FLASH sector.
• PSEE (Program Store Erase Enable) is set to erase an entire page of the FLASH program memory provided the PSWE bit is also set.
• PSWE (Program Store Write Enable) is set to allow the MOVX instruction to write a byte of data to FLASH program memory.
