SNSK & SNS pins are on thesame port, number of channels =2• If the use of SNS1(A) and SNSK1(A) pins are on the same port,the user should always have the configuration (PA0, PA1) & (PA2,PA3). In this case channel 0 will be on (PA0, PA1) pins; channel 1will be on (PA2, PA3) pins. The even pins of the port are used asSNS1 pins and odd pins of the port are used as SNSK1 pins• When pin configurability is used, sensors should be mounted onthe pins as selected as per the rules illustrated in section 5.8.1 andchannels should be assigned as given in section 5.6.6.1.1.4SNSK & SNS pins are on thesame port, number of channels =4• If the use of SNS1(A) and SNSK1(A) pins are on the same port,the user should always have the configuration (PA0, PA1), (PA2,PA3), (PA4, PA5) & (PA6, PA7). In this case channel 0 will be on(PA0, PA1) pins, channel 1 will be on (PA2, PA3) pins and so onup to channel 4 will be on (PA6, PA7) pins. The even pins of theport are used as SNS1 pins and odd pins of the port are used asSNSK1 pins, when pin configurability is not being used.• When using pin configurability, sensors should be mounted on thepins as selected as per the rules illustrated in section 5.8.1 andchannels should be assigned as given in section 5.6.6.1.1.4SNSK & SNS pins are on thesame port, number of channels =16( Available only for UC3 devices ifmore than 4 channels are to beused on a single port.
