Subject: es519xx: fix switching between frequency and duty cycle mode on 14 bytes chips
X-Git-Tag: libsigrok-0.3.0~366

es519xx: fix switching between frequency and duty cycle mode on 14 bytes chips

Here is what the datasheet says about this:
  "If judge bit is 1, it means frequency mode. If judge bit is 0,
   it means duty cycle mode."
But this is plain wrong. Reality proves this is the other way around.
