Subject: mx25l1605d SPI dump: Add fixed capture.
X-Git-Tag: sigrok-dumps-0.1.0~58
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=f28b538fa3cb12966a90c1b1cff741d6cd08d40e;p=libsigrokdecode.git

mx25l1605d SPI dump: Add fixed capture.

The last capture was completely bogus as the sample rate used was way
too low. This a re-capture of the same data using a ChronoVu LA8 logic
analyzer at 25MHz sample rate.
