(2) NOTE: Do not use this pin as RTCCLK output if the DMAE0 functionality is used on any other pin. Select an alternative RTCCLK output
pin.
(3) Setting P1SEL1.x and P1SEL0.x disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
(4) Setting the CEPD.x bit of the comparator disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals. Selecting the Cx input pin to the comparator multiplexer with the input select bits in the comparator module
automatically disables output driver and input buffer for that pin, regardless of the state of the associated CEPD.x bit.
(5) NOTE: Do not use this pin as COUT output if the TA1CLK functionality is used on any other pin. Select an alternative COUT output pin.
(6) NOTE: Do not use this pin as COUT output if the TA0CLK functionality is used on any other pin. Select an alternative COUT output pin.
