c. The primary oscillator on explorer 16 is connected between two pins of the Microcontroller. Mention the name/names and the number of those pin.

The primary oscillator is connected between pins OSC1 (pin 63) and OSC2 (pin 64) of the Microcontroller.

what is the other rows of the oscillator?

The other rows of the oscillator typically consist of the necessary capacitors and resistors connected to pins OSC1 and OSC2. These components are needed for the proper functioning of the oscillator circuit.

The other rows of the oscillator include the power supply connections and the necessary capacitors on both sides of the crystal. These connections are made between pins VSS and VDD of the Microcontroller and the ground and power supply respectively. Additionally, there might be a load capacitor connected between each crystal pin and ground.

The primary oscillator typically consists of more components than just the two pins OSC1 and OSC2. The full oscillator circuit includes additional components such as capacitors and resistors that are required for stable oscillator operation. These components are connected in parallel to the oscillator pins OSC1 and OSC2.

The values of the capacitors and resistors in the oscillator circuit can vary depending on the specific oscillator design, target frequency, and the requirements of the microcontroller or oscillator module being used. It is necessary to refer to the datasheet of the microcontroller or the specific oscillator module to determine the exact values of these components.

It is also important to note that the primary oscillator circuit may have additional pins or connections for features such as an external clock input, clock output, enable/disable control, or other oscillator-related functions. These additional pins or connections vary depending on the specific microcontroller or oscillator module in use. Again, referring to the appropriate datasheet will provide the necessary details.
