Tool/software: Code Composer Studio

Dear community,

i am using TMS570LS1227.

my question is ADC channel.

i want to using ad1in[15]/ad2in[15](pin num 85) and ad1in[17]/ad2in[1](pin num 59).

Can I connect either ad1in [15] or ad2in [15](ad1in[17] or ad2in[1]) to connect those two pins?

if i want to connect pin num 85 pin, in halcogen, can i connect channel group1 enable pin num 15 or group2 channel 15?

Regards,

    Hello,

    ADC1IN[15] and AD2IN[15] share pin 85, and AD1IN[17] and AD2IN[1] share pin 59. You can use both ADC1 and ADC2 for the shared ADC channels (for example 15 on pin 85). If you use it for both ADC1 and ADC2 for a shared channel, the sample windows must be identical such that the sample windows completely match each other.
