), respectively, as shown in the following table. Port 1 also receives the low-order address bytes during Flash programming and verification.
Table 4.1
Port 2
Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. The Port 2 output buffers can sink/source four TTL inputs. When 1s are written to Port 2 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups.
Port 2 emits the high-order address byte during fetches from external program memor..................[:=> Show Contents <=:]

this circuit.) Comparator LM311 (IC1) compares the level set at pin 3 (nearly 6V, set using a 47k pot) with the level at pin 2. When light is falling on LDR1, its voltage is above 1V and IC5 has a low output at its pin 1. When no light is falling on LDR1, its voltage drops below 1V and IC1 output at its pin 1 becomes high.
The output from the Op-amp is given as the clock for seven segment counter 4033.The counter count 1 for each high going pulse.The 4033 encodes the count to display number in seven segment display CE c5611
