RX23W Group 44. 12-Bit A/D Converter (S12ADE)
44.2.24 A/D Compare Function Window A Extended Input Comparison Condition
Setting Register (ADCMPLER)
The ADCMPLER register sets the condition for use in comparing the values of ADCMPDR0 and ADCMPDR1 registers
with results of A/D conversion.
The ADCMPLER register should be set while ADCSR.ADST is 0.
CMPLTSA Bit (Compare Window A Temperature Sensor Output Comparison Condition Select)
This bit sets the condition for use in comparison with temperature sensor output to which compare window A conditions
are applied.
When the result of comparison matches the set condition, the ADCMPSER.CMPSTTSA flag is set to 1.
Figure 44.3 shows the comparison conditions.
CMPLOCA Bit (Internal Reference Voltage Comparison Condition Select)
This bit sets conditions for use in comparison with internal reference voltage to which compare window A conditions are
applied.
When the result of comparison matches the set condition, the ADCMPSER.CMPSTOCA flag is set to 1.
Figure 44.3 shows the comparison conditions.
