RX23W Group 44. 12-Bit A/D Converter (S12ADE)
44.2.23 A/D Compare Function Window A Comparison Condition Setting Register 1
(ADCMPLR1)
The ADCMPLR1 register sets the condition for use in comparing the values of the ADCMPDR0 and ADCMPDR1
registers with results of A/D conversion.
The ADCMPLR1 register should be set while ADCSR.ADST bit is 0.
CMPLCHA1n Bit (n = 00 to 04, 11) (Compare Window A Comparison Condition Select)
This bit sets the condition for use in comparison with the selected channel from among AN016 to AN020 and AN027 to
which compare window A conditions are applied. A condition can be set for individual comparison of each analog input.
The CMPLCHA100 bit is used for AN016 and the CMPLCHA111 bit is used for AN027.
When the result of comparison matches the set condition, the ADCMPSR1.CMPSTCHA1n flag is set to 1.
Figure 44.3 shows the comparison conditions.
