Port 1 pins that have 1's written to them are pulled high by the internal pullup resistors, and in that state can be used as inputs. As inputs, port 1 pins being externally pulled low will source current (I IL, in the DC characteristics) because of the internal pullup resistors. The port is used for the low-order address byte during program verification. Port 1 also contains the interrupt, timer, clock, capture and compare pins that are used by various options. The output latch corresponding to a secondary function must be programmed to a one (1) for that function to operate (except when used for the compare functions). The secondary functions are assigned to the port 1 pins as follows: P1.0 INT3 CC0 Interrupt 3 input / compare 0 output / capture 0 input P1.1 INT4 CC1 Interrupt 4 input / compare 1 output / capture 1 input P1.2 INT5 CC2 Interrupt 5 input / compare 2 output / capture 2 input P1.3 INT6 CC3 Interrupt 6 input / compare 3 output / capture 3 input P1.4 INT2 Interrupt 2 input P1.5 T2EX Timer 2 external reload / trigger input P1.6 CLKOUT System clock output P1.7 T2 Counter 2 input Ground (0V) during normal, idle, and power down operation.

To drive the device from an external clock source, XTAL2 should be driven, while XTAL1 is left unconnected. Minimum and maximum high and low times as well as rise/ fall times specified in the AC characteristics must be observed. XTAL1 is the output of the inverting oscillator amplifier. This pin is used for the oscillator operation with crystal or ceramic resonator. Port 2 is an 8-bit quasi-bidirectional I/O port with internal pullup resistors. Port 2 pins that have 1's written to them are pulled high by the internal pullup resistors, and in that state can be used as inputs.
