P1.0/P1.1
I/O
P1.0 and P1.1 can function as a digital inputs or digital outputs and have a
pull-up configuration as described below for Port 3. P1.0 and P1.1 have an
increased current drive sink capability of 10 mA.
P1.0/T2/PWM0
I/O
P1.0 and P1.1 also have various secondary functions as described below.
P1.0 can also be used to provide a clock input to Timer 2. When enabled, counter
2 is incremented in response to a negative transition on the T2 input pin.
If the PWM is enabled, the PWM0 output will appear at this pin.
P1.1/T2EX/PWM1 I/O
P1.1 can also be used to provide a control input to Timer 2. When enabled, a
negative transition on the T2EX input pin will cause a Timer 2 capture or reload
event. If the PWM is enabled, the PWM1 output will appear at this pin.
