TC23x Port configuration

Hello to all!

I have some misunderstanding with the ports configuration. In TC23x datasheet it is shown that port can act as an analog input:
3753.attach

3752.attach

But in the User Manual there is no such mode, only simple input/output:

3754.attach

How can I make P15.1 act as an analog input (SCU_EVRWUPB signal) ?

Thank in advance!

Re: TC23x Port configuration

Hi mcrt. EVRWUPB refers to the use of P15.1 as the "Pin B" wakeup signal - see 8.3.2.4 Standby Mode on page 504 of tc23x_tc22x_um_v1.1.pdf. I suspect the "AI" here means that there's a hidden ADC inside the "Wake-up Unit" in Standby mode.
