8 Using <Auto-Program> to program a target device

The most straightforward method of programming a target device is to select

<Device><Auto-Program> or click the <Auto-Program> icon.

An ‘Auto-Program’ performs the following actions:

- Pre-programming State Machine operations

- Check Signature

- Chip Erase

- Blank check

- Write CODE area

- Verify Pass 2 (Default: OFF)

- Write special Options (Status Byte)

- Write Security

Please note:

The ‘Status Byte’ is automatically cleared to zero at the end of any programming

operation. This makes sure that the user target code starts execution the next time the

device comes out of RESET.

9 Using the <Device> commands individually

It is possible to initiate any programmer command individually from the <Device> menu.

Please note:

i. The programmer will, by default, perform a ‘Pre-programming State machine’ operation

and a ‘Check Signature’ for each operation selected. The ‘Check Signature’ can be

disabled using a tick box in the <Options><Advanced> menu.

ii. The <Device><Write> operation does not perform a ‘Chip Erase’ operation. If there is

already non-FF data in the target device, then the ‘Write’ operation will fail. A manual

<Device><Erase> is required to erase the device.

iii. The <Device><Special Options> operation allows the user to read the current value of

the ‘Status Byte’ from the target device. New values can also be written to the target

device.
