As Figure 26 shows, pressing the Program OTP All Channels button allows you to program a gamma

curve into the nonvolatile memory in the BUF22821. All 22 channels (including the VCOM channels) are

then programmed simultaneously. The values are stored in the memory bank that is selected via the

BKSEL switch (see Section 4.4).
