0: Device is powered up and operational in either a direct or
autonomous conversion mode (see AMODE[1:0] below).
1: Device is powered down, OTP is held in reset
00: Direct conversion mode (AUTO = 0)
01: Autonomous X and Y scan (AUTO = 1)
10: Autonomous X, Y, Z1 scan (AUTO = 1)
11: Autonomous X, Y, Z1, Z2 scan (AUTO = 1)
0: Disregard aperture criteria
1: Enable aperture criteria (spatial filter)
(applies to autonomous modes only)
0: Use median averaging filters (ignore outliers)
1: Use straight averaging filters
0: Disable (X, Y) position averaging in selected mode
1: Enable (X, Y) position averaging in selected mode
0: Disable (Z1, Z2) pressure averaging in selected mode
1: Enable (Z1, Z2) pressure averaging in selected mode
