The maximum clock frequency for the LPC2366 is 72 MHz, but it can be overclocked to 80 MHz with some limitations.
The pin multiplexing on the LPC2366 can be configured using the PINSELx registers, where x is the number of the register. Each register controls the function of a group of pins.
The maximum amount of current that can be sourced or sunk by the GPIO pins on the LPC2366 is 4 mA.
The ADC on the LPC2366 can be used by configuring the ADC clock, selecting the ADC channel, and starting the ADC conversion. The ADC result can be read from the ADCR register.
The bootloader on the LPC2366 is used to load the application code into the flash memory of the microcontroller. It can be used to update the firmware of the device in the field.
