Description
When TEMP_PER = 0 automatic temperature measurements are disabled, and
TEMP_START may be set by the MPU to initiate a one-shot temperature
measurement. TEMP_START is ignored in SLP mode. Hardware clears TEMP_START
when the temperature measurement is complete.
Selects one of 32 signals for TMUXOUT. See
Selects one of 32 signals for TMUX2OUT. See
The silicon version index. This word may be read by firmware to determine the silicon
version.
Brings the ADC reference voltage out to the VREF pin. This feature is disabled when
VREF_DIS=1.
Disables the internal ADC voltage reference.
This word describes the source of power and the status of the VDD.
Timer duration is WAKE_TMR+1 seconds.
Reset the WD timer. The WD is reset when a 1 is written to this bit. Writing a one
clears and restarts the watch dog timer.
The TMUX setting for the remote isolated sensors (71M6xx3).
