Description
Causes VBAT to be measured whenever a temperature measurement is performed.
Selects which battery is monitored by the temperature sensor:
1 = VBAT, 0 = VBAT_RTC
Sets the period between temperature measurements. Automatic measurements can be
enabled in any mode (MSN, BRN, LCD, or SLP). TEMP_PER = 0 disables automatic
temperature updates, in which case TEMP_START may be used by the MPU to initiate a
one-shot temperature measurement.
TEMP_PER Time (seconds)
0
No temperature updates
1-6
2^{(3 + TEMP _ PER)}
7
Continuous updates
Selects the power source for the temp sensor:
1 = V3P3D, 0 = VBAT_RTC.
This bit is ignored in SLP and LCD modes, where the temp sensor is always powered
by VBAT_RTC.
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 and LCD modes. Hardware clears
TEMP_START when the temperature measurement is complete.
Selects one of 32 signals for TMUXOUT. See 2.5.14 for details.
Selects one of 32 signals for TMUX2OUT. See 2.5.14 for details.
The TMUX setting for the remote isolated sensors (71M6xx3).
The silicon version index. This word may be read by firmware to determine the silicon
version.
