Warnings and Troubleshooting
5.1
No IC or IC Inserted Incorrectly
1. See
. Error message pops up.
2. Discard the IC if IC is inserted incorrectly
5.2

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)
error message pops up.
(b) Go to
. . If OTP matches, then the IC is already programmed to proper trim value. If OTP
