M0516LDE - Nuvoton

M0516LDE Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the M0516LDE?
  The M0516LDE can operate up to 50 MHz, but the recommended operating frequency is up to 48 MHz for optimal performance and power consumption.
• How do I configure the clock source for the M0516LDE?
  The M0516LDE can use an external crystal oscillator or an internal RC oscillator as the clock source. The clock source can be selected using the CLK_SEL bits in the Clock Control Register (CLK_CFG).
• What is the purpose of the VBAT pin on the M0516LDE?
  The VBAT pin is used to connect a battery or a supercapacitor to provide power to the real-time clock (RTC) and the backup registers when the main power supply is turned off.
• How do I use the ADC on the M0516LDE?
  The M0516LDE has a 12-bit ADC with up to 16 channels. To use the ADC, configure the ADC clock, select the channel, and start the conversion using the ADC control register. The ADC result can be read from the ADC data register.
• What is the maximum current that can be sourced or sunk by the GPIO pins on the M0516LDE?
  The GPIO pins on the M0516LDE can source or sink up to 4 mA of current. However, the total current sourced or sunk by all GPIO pins should not exceed 100 mA.
