Peripheral Simulation

For Analog Devices ADuC7024 — Flash/EE 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/EE Memory Dialog

The Flash/EE Memory dialog displays and configures the on-chip Flash/EE Memory provided with the ADuC7000 series devices. The controls in this dialog are separated into several logical groups.

Flash/EE Status Group

• FEESTA (Flash/EE Status Register) contains the following Flash/EE status bits:
• Command Complete is set when a command successfully completes.
• Command Fail is set when a command does not successfully complete.
• Controller Busy is set when the Flash/EE controller is busy.
• Interrupt Status is set when a command completes and the Flash/EE interrupt enable bit is set.
• Burst Command is set when a burst command is sent to the Flash/EE controller.

Flash/EE Command Group

• FEECON (Flash/EE Command Register) contains the current Flash/EE command.

Flash/EE Data Group

• FEEDAT (Flash/EE Data Register) contains the current Flash/EE data value.

Flash/EE Address Group

• FEEADR (Flash/EE Address Register) contains the current Flash/EE address where the current data will be loaded or written to.

Flash/EE Mode Group

• FEEMOD (Flash/EE Mode Register) contains only the Flash/EE interrupt enable bit.
• Interrupt Enable is set when the Flash/EE interrupt is enabled.

Flash/EE Signature Group

• FEESIGN (Flash/EE Signature Register) displays the 24-bit Flash/EE signature value.

Flash/EE Protection Group

• FEEPRO (Flash/EE Protection Register) contains the composite Flash/EE protection setting. It is protected by a 32-bit access key value which must be written to FEEDAT and FEECON.
• FEEHIDE (Flash/EE Hide Register) contains the read protection and write protection settings below. These settings can be written to FEEPRO only after the proper access key is provided.
• Read Protection is set to prevent the Flash/EE from being read through JTAG or parallel programming modes.

Write Protection Page Group

• n..m sets write protection for pages in groups of 4. n is the low page number, m is the high page number.
