How many and what are the clock sources available for the Microcontroller in Explorer 16 board?
The Explorer 16 board is an evaluation board for Microchip PIC microcontrollers. It provides several clock sources for the microcontroller. The available clock sources are:
1. Primary Oscillator (POSC): This is an external crystal oscillator that can be connected to the board. It provides a high-precision clock source for the microcontroller.
2. Timer1 Oscillator (T1OSC): This is an internal oscillator module used specifically by Timer1. It can be used as a low-frequency clock source for Timer1 operations.
3. INTRC Oscillator: This is an internal oscillator with a fixed frequency of around 8 MHz. It provides a relatively low-precision clock source for the microcontroller.
4. FRC Oscillator: This is an internal oscillator with a fixed frequency of 7.37 MHz or 8 MHz. It provides a fast clock source for the microcontroller.
5. LFINTOSC Oscillator: This is an internal low-frequency oscillator with a fixed frequency of around 31 kHz. It is often used for low-power operations and real-time clocks.
6. SOSC Oscillator: This is an external secondary oscillator that can be connected to the board. It provides a low-frequency clock source for the microcontroller.
These are the main clock sources available on the Explorer 16 board for the Microchip PIC microcontrollers.
The Explorer 16 board features several clock sources for the microcontroller, which vary depending on the specific version of the board. Here are some common clock sources found on the Explorer 16 board:
1. Primary clock oscillator (X1, X2): The board generally includes a crystal oscillator that connects to pins X1 and X2 of the microcontroller. This crystal provides a stable frequency as the main clock source.
2. Secondary oscillator (X3, X4): Some versions of the board also include a secondary oscillator. This oscillator is typically used to drive the Real-Time Clock (RTC) module on the board.
3. External clock input (CLKIN): The board may feature a CLKIN pin that allows an external clock signal to be used as the microcontroller's clock source. This can come from an external oscillator or another clock-generating device.
4. Internal clock source (FRC): The microcontroller itself can generate its own clock using the Fast RC Oscillator (FRC). This internal clock source is not as accurate as a crystal oscillator but can be useful for initial testing and development.
5. Peripheral clock sources: The microcontroller provides various peripheral clock sources that can be configured to different frequencies. These clocks are derived from the primary oscillator or other clock sources and are used to drive specific peripherals, such as timers, UARTs, and SPI modules.
It's important to refer to the specific documentation and datasheet for the version of the Explorer 16 board you are using to get precise details on the available clock sources and their connections.
