Description
EEE Minimum Assert 31:16 RW 0x0 The minimum time from start of LPI message
transmission to end of LPI message
transmission.
EEE Exit Time 15:0 RW 0x190 Time from the end of LPI message transmission
to when normal transmission is allowed again.

Description
Reserved 31:5 RW 0x0 –
Freeze 2s Average 4 RW 0x0 Stop the update of the 2 second average register.
The accumulation and holding registers will still
update.
Freeze Count 3 RW 0x0 Stop the accumulation process of the PDRIVE
samples. This effectively disables the cur_meas
block, and freezes all values of registers. This bit
can be set to stop the register updates for
register reads, and then restarted.
Recalibrate 2 RW 0x0 Restart the calibration process and capture a
single 500 µs accumulation period.
