The recommended operating voltage range for P87LPC762FN,112 is 2.4V to 3.6V.
The oscillator can be configured using the OSCCFG register. The oscillator frequency can be set to either 12 MHz or 14.7456 MHz using the OSCCFG register.
The maximum clock frequency supported by the P87LPC762FN,112 is 14.7456 MHz.
The UART on the P87LPC762FN,112 can be used by configuring the UART registers (UARTn_LCR, UARTn_MCR, UARTn_DLL, UARTn_DLM) and enabling the UART clock using the PCONP register.
The WAKEUP pin is used to wake up the microcontroller from a low-power mode (e.g. sleep mode) when an external interrupt is triggered.
