The recommended operating voltage range for P87LPC762BD,512 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 24 MHz, and the oscillator type can be set to either internal or external.
The maximum clock frequency for the P87LPC762BD,512 is 12 MHz.
The UART on the P87LPC762BD,512 can be used by configuring the UART registers (UARTn_LCR, UARTn_MCR, UARTn_DLL, UARTn_DLM) and enabling the UART clock. The UART can operate in asynchronous mode or synchronous mode.
The watchdog timer on the P87LPC762BD,512 is used to reset the microcontroller if it becomes stuck in an infinite loop or if a software fault occurs. The watchdog timer can be enabled or disabled using the WDT_CTRL register.
