Write
Selecting Write from the Program menu applies the entire programming sequence. This
sequence is listed below.
1. The host PC detects the OCD hardware and its connection with the target device.
2. All connected target devices are processed simultaneously.
3. The ISP erases the target device with a bulk erase algorithm.
4. The ISP next programs the code area.
5. The ISP verifies the code area.
6. The ISP programs the configuration area.
7. The ISP verifies the configuration area.
Verify
Selecting Verify from the Program menu initiates a comparison of the contents of the ISP
programmer’s buffer with the contents of the target device’s memory. This verification
sequence is described below.
1. The host PC detects the OCD hardware and its connection with the target device.
2. All connected target devices are processed simultaneously.
3. The ISP checks whether the target device is locked or unlocked. If the target is locked,
verification is canceled.
4. The ISP verifies the code area.
5. The ISP verifies the configuration area.
Erase
Selecting Erase from the Program menu causes the entire contents of the target device’s
memory, including configurations, to be erased. This erasure sequence is described below.
1. The host PC detects the OCD hardware and its connection with the target device.
2. All connected target devices are processed simultaneously.
3. The ISP erases the target device, whether it is locked or unlocked.
Blank Check
The Blank Check function determines if the target device is blank (entirely erased) after an
erasure. The sequence of this Blank Check function is described below.
1. The host PC detects the OCD hardware and its connection with the target device.
2. All connected target devices are processed simultaneously.
