bit[15:0] COUNT
The value returned by this register depends on whether the External Counter Reset Input
function is enabled or not. The External Counter Reset Input is enabled when EXT_SEL of
MSC_CTRL [0x02(W1)] bit [7:6] = 01.
When the External Counter Reset Input function is disabled, this register returns the sampling
count value of the internal A/D converter.
NOTE: The time unit of the sampling counter value represents 250 μs/count.
Example: If the data output rate equals 2000Sps, the counter value sequence is 0, 2,4,6, ... ,
0xFFFE, 0, 2, ....
When the External Counter Reset Input function is enabled, this register returns the timer
counter value used by the External Counter Reset Input function.

bit[15:0] Temperature sensor output data
The internal temperature sensor value can be read.
The output data format is 32-bit two's complement format. For 16-bit usage, treat the data as 16-
bits two's complement using the upper 16-bits (TEMP_HIGH).
Please refer to the below formula for conversion to temperature in centigrade. Please refer to
Table 2.3 Sensor Specification for the scale factor value.
For 32-bit usage:, T [℃]= (SF/65536) * ( A + 997064704 ) + 25
For 16-bit usage: T [℃]= SF * ( A + 15214 ) + 25
SF : Scale Factor
A: Temperature sensor output data (decimal)
NOTE: The reference value in this register is for the temperature correction. There is no guarantee
that the value provides the absolute value of the internal temperature.
