Description
Storage location for STEMP at 22C. STEMP is an 11-bit word.
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
Indicates that hardware is still writing the 0x28A0 byte. Additional writes to
this byte will be locked out while it is one. Write duration could be as long as
6ms.
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.
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.
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.
