Figure 16. Completed EPROM Programming. Insert a New IC and Repeat From Step 5.
5 Warnings and Troubleshooting
5.1 No IC or IC Inserted Incorrectly
1. See Figure 17. Error message pops up.
2. Discard the IC if IC is inserted incorrectly
5.2 Reprogramming Trimmed (Programmed) IC
EPROM (OTP) is a one-time-only programmable memory. ICs must not be programmed more than one
time. It is possible to damage the device if programmed twice.
(a) Figure 18 error message pops up.
(b) Go to Section 6.4. . If OTP matches, then the IC is already programmed to proper trim value. If OTP
does not match, then IC is a failed IC and must be disregarded.
(c) Go to Section 6.5. Verify Blank Check feature. Request that TI send blank ICs.
