USB Full speed, HXT, Crystal accuracy, PLL Jitter How to calculate the necessary HXT accuracy(ppm) for a full speed USB device? 1520404960076 There is an accuracy parameter (ppm) for any external crystals, for example 12M+/-100ppm, and there are independent clock source from full speed USB device and hos. USB SPEC. has defined a frame timer range to be 500ppm. Below is USB2.0 Spec. definition about frame timer range in ppm. Nuvoton has no constrain of the crystal accuracy and user can calculate the effect to USB by the following calculation. (PFM-M487 has HXT with +/-30ppm) There are two major errors contribute to USB clock, one is the crystal accuracy and the other is PLL jitter. Crystal ppm contribution – For a 100ppm crystal pass through the PLL to the USB clock has still 100ppm at the end of USB clock. PLL Jitter contribution – By datasheet, the maximum PLL jitter is 250ps (RMS, Figure1). PLL Jitter (192MHz) pass to USB (12M) has a divider of 16 timers and 250ps jitter will
FAQ / In the program development process, how to confirm if a register value is correct?
https://www.nuvoton.com/support/technical-support/faq/d62575f6-04f1-11ea-b113-05daf7eedf03/
In the program development process, how to confirm if a register value is correct? 1450683600000 In Debug mode under the Keil RVMDK development environment, the System Viewer window can be used for monitoring register values; in Debug mode under the IAR EWARM development environment, the SFR (Special Function Register) is provided for users to confirm register values. In the Stop/Break state, the user can change the register value, but the register with the Write-protect function can only be written after unlocked. Keil RVMDK: After the Nu-Link Driver for Keil RVMDK is installed, the user can set an import file name of the System Viewer File through Project→Options for Target→Target page, as shown below. If the pre-selected import file is different from the chip series used, the user can enable the “Use Custom File” option and re-select an import file. The file path is (Keil RVMDK installation path)\ARM\SFD\Nuvoton. After entering Debug mode, the user can open a register to monitor
