The user can tie two or more D port outputs (except D2) together in order to get a higher drive. NOTE Care must be exercised with the D2 pin operation. At RESET, the external loads on this pin must ensure that the output voltages stay above 0.7 VCC to prevent the chip from entering special modes. Also keep the external loading on D2 to less than 1000 pF. Figure 4-2. I/O Port Configurations Figure 4-3.
