The recommended power-up sequence is to apply power to the VCC pin first, followed by the VDD pin. This ensures that the internal voltage regulators are properly initialized.
The I2C interface on the LPC_140_CTP is configured through the I2C Control Register (ICR). The ICR register is used to set the I2C clock frequency, slave address, and other I2C-related settings.
The maximum clock frequency supported by the LPC_140_CTP is 72 MHz. However, the actual clock frequency may be limited by the specific application and system requirements.
The LPC_140_CTP has a built-in watchdog timer that can be enabled and configured through the Watchdog Timer Control Register (WTCR). The WTCR register is used to set the watchdog timer period, enable or disable the watchdog timer, and configure other watchdog timer-related settings.
The JTAG interface on the LPC_140_CTP is used for debugging and testing purposes. It allows developers to access the internal registers and memory of the LPC_140_CTP using a JTAG debugger or emulator.
