19.2.7 Temperature Sensor Enable Register (TEMPEN, M3[0Ch])
Bits 7:1: Reserved
Bit 0: Temperature Sensor Enable (TSEN). This bit enables/disables the on-board temperature sensor whose value
can be read through ADC channel 6 (single-ended mode only).
0 = Temperature sensor is disabled (default value).
1 = Temperature sensor is enabled.
19.3 Analog-to-Digital Converter Code Examples
19.3.1 ADC Example 1: Single Conversion
move ADCN, #0300h ; Set ADC clock to sysclk/8 (78ksps at 10MHz)
move ADST, #0010h ; Points ADDATA to config register 0
move ADDATA, #06h ; Single-ended conversion on channel AN6, AVDD ref
move ADST.6, #1 ; Start conversion
waitConvert:
move C, ADST.6
jump C, waitConvert ; Conversion has completed when ADST.6 clears to 0
move ADST, #0000h ; Points ADDATA to data register 0
move Acc, ADDATA ; Get conversion result
19.3.2 ADC Example 2: Continuous Conversion
move ADCN, #0F00h ; Set ADC clock to sysclk/8 (78ksps at 10MHz),
; also set Data Available interrupt to trigger
; following every 16 samples
move ADCN.6, #1 ; Enable continuous conversion mode
move ADST, #0010h ; Points ADDATA to config register 0
move ADDATA, #06h ; ACFG[0]: Single-ended conversion on AN6, AVDD ref
move ADDATA, #07h ; ACFG[1]: Single-ended conversion on AN7, AVDD ref
move ADADDR, #0001h ; Sequence runs from ACFG[0] to ACFG[1] inclusive
move ADST.6, #1 ; Start conversion (continuous)
